OTHER FISH 1-3
JUST DISCOVERED AND NAMED SPECIES !!!!
Oryzias woworae
Scientific Name: Oryzias woworae, Parenti & Hadiaty, 2010
Size: 1"-1.5" SL
Distribution: A freshwater habitat on Muna Island off the southeastern coast of the main island of Sulawesi, Indonesia
Temperature: 22.0-30.0°C or 72.0-86.0°F
Feeding: These fish are currently eating Sera Baby Vipagran, Sera O-Nips, Sera Viformo, flake and baby brine shrimp.
Breeding: Keeping and breeding this cute fish is very easy and even beginners in the hobby will be successful. These ricefishes can be kept in moderate hard water, it is thus usually not necessary to mix a special water for them. In all Oryzias species, the female carries the eggs some time along with it after spawning and strips them then on dainty waterplants. Hatching depends on the water temperature, but it takes usually between 2 and 3 weeks. The adults do not show any interest in the eggs, which can be left in the breeding tank. The newly hatched offspring swims immediately under the water surface. Although they are very tiny, they can be easily recognized by the shining eyes that look like a spark. One should separate them now by using a spoon and rear them in a separate tank.
Oryzias woworae, a new species of ricefish, is described from a freshwater habitat on Muna Island off the southeastern coast of the main island of Sulawesi, Indonesia. The new species is distinguished from all other known ricefishes by a remarkable color pattern of both sexes in life: the ventral surface of head and body anterior to the pelvic fins, dorsal portion of pectoral fins, dorsal-fin base, posterior portion of anal-fin base, caudal peduncle, and dorsal and ventral portions of caudal fin are brilliant red; the midlateral scales from just posterior to the eye to the caudal-fin base and the body scales anterior to the anal fin and ventral to midlateral scales are steel blue; the blue coloration is most prominent in adult males. Oryzias woworae, the smallest known ricefish from Sulawesi, is hypothesized to be a member of an unnamed clade of ricefishes diagnosed by a truncate, rather than lunate or emarginate, caudal fin. Description of O. woworae brings the recognized number of species in the beloniform family Adrianichthyidae to 29, 13 of which are endemic to Sulawesi. Ricefishes, in particular the new species, may serve as icons to generate interest in conservation of the endemic freshwater biota of Sulawesi.

OTHER FISH 1-4
Boraras brigittae aka Chili Rasbora
Common Name: Mosquito Rasbora, Chili Rasbora
Family: Cyprinidae
Distribution: Appears to be endemic to southwestern Borneo though occurence records are scant. The type locality is given as Bandjarmasin, a port town in the Indonesian province of South Kalimantan (Kalimantan Selatan).
Habitat: Inhabits black water streams and pools associated with ancient forest peat swamps. The water is stained brown due to the release of tannins and other chemicals released by decomposing organic matter and the substrate scattered with fallen leaves, twigs and branches. Such environments characteristically contain very soft (negligible hardness), acidic (pH as low as 4.0) water and are often dimly-lit due to the forest canopy above and dense marginal vegetation. Across much of Southeast Asia these precious biotopes are under threat from rubber/palm oil plantations, building developments and other human activities.
Size: 1.2"/3.5cm.
Housing: Though small it still needs space to swim and dominant males will form temporary territories when spawning so a group is best kept in a tank measuring at least 18" x 10" x 10"/45cm x 25cm x 25cm/29.5 litres. Best kept in a densely-planted tank and is an excellent choice for the carefully-aquascaped set-up. The addition of some floating plants and driftwood roots or branches to diffuse the light entering the tank also seems to be appreciated and adds a more natural feel. Filtration does not need to be particularly strong as it mostly hails from sluggish waters and may struggle if there is a fast current. A soft, sandy substrate is probably the best choice to which can be added a few driftwood roots and branches, placed in such a way that plenty of shady spots are formed. The addition of Sera Blackwater Aquatan or Sera Peat would further emphasize the natural feel and as well as offering even more cover for the fish brings with it the growth of microbe colonies as decomposition occurs.
Temperature: 77 - 82°F/25 - 28°C
pH Range: 5.0 - 7.0
Hardness: 5 - 10°H
Diet: As with other Boraras species it is likely to be a micropredator feeding on small insects, worms, crustaceans and other zooplankton in nature. In the aquarium it will accept dried foods of a suitable size but should not be fed these exclusively. Daily meals of small live and frozen fare such as Daphnia, Artemia along with good quality flakes and granules will result in the best colouration and encourage the fish to come into breeding condition.
Compatibility: This species is very peaceful but does not make an ideal community fish due to its small size and rather timid nature. It will do best when maintained alone or with other diminutive species such as Odontocharacidium, Microdevario, Sundadanio, Danionella, Eirmotus, Trigonostigma, pygmy Corydoras and small Loricariids such as Otocinclus. It's a shoaling species by nature and really should be kept in a group of at least 8-10 specimens. Maintaining it in decent numbers will not only make the fish less nervous but will result in a more effective, natural-looking display. Males will also display their best colours and some interesting behaviour as they compete with one other for female attention.
Sexual Dimorphism: Mature females are noticeably rounder-bellied and often a little larger than males. Males are generally more attractive with dominant individuals often displaying intense colouration.
Breeding: Like many small cyprinids this species is an egg-scattering, continuous spawner that exhibits zero parental care. That is to say when in good condition and in the presence of both males and females relatively small numbers of eggs will be laid daily. In a well-furnished, mature aquarium it is therefore possible that small numbers of fry may start to appear without human intervention. However if you want to increase the yield of fry a slightly more controlled approach is required. These should be very dimly lit with the base either left bare or covered with some kind of mesh of a large enough grade so that any eggs that fail to adhere to the plant can pass through but small enough so that the adults cannot reach them. The water itself should be of pH 5.0-6.5, 1-5°H with a temperature towards the upper end of the range suggested above. A decent-sized clump of Java moss or other fine-leaved plant should also be added filling perhaps half the available space. Filtration is not really necessary but you can use a small, air-powered sponge filter if you prefer. Two or three pairs of well-conditioned adult fish should then be introduced to each container. It is wise to make the transfer slowly in order to avoid excessive levels of stress but if conditions are to their liking they should begin to spawn the following morning. Once spawning has commenced it should continue on a daily basis. The pair(s) should be left in for no more than a couple of days before being removed as the first eggs should hatch by the second day after the initial spawning. The tiny young will survive on their yolk sacs for another 24 hours or so after which they will require Paramecium or other microscopic food. After a week to ten days they should be large enough to accept Artemia nauplii/microworm etc. As the days pass additional fry should start to appear from later spawning events. It's best to wait a week or two before starting to perform small water changes in order to avoid unduly shocking the young fish.

Nannostomus espei aka Barred pencilfish
Origin: Guyana, Mazaruni river system
Description: Most of the pencils sport one to three horizontal lines during daylight, but they dress in vertical bars when the lights go out. This is where Nannostomus espei stands out from the other 15 species of pencils - it displays vertical bars all the time with the horizontal lines subtly visible as a background pattern.
Care: Very rare and sometimes difficult fish to keep. Because of this it's best to keep them in a 60-80cm species tank, or combined with small peaceful fish that have similar requirements. A large school of this fish should be purchased, best 10 or more. Subdued light, floating plants, densely planted sides and back, with some free swimming space in the front create a suitable setup for these fish. As a substrate either a thin layer of brown sand, or dark gravel. Frequent small waterchanges are required, and the water should be well filtered, best over Sera Super Peat. If the fish are kept well, they will show themselves frequently, and reside near the surface of the tank.
Temperature: 22-26 °C / 72-78 °F
Feeding: Small live and frozen food as well as flake and micropellets.
Size: Up to 4 cm / 1.5"
pH: 5.5 - 7.0; dH range: 4.0 - 10.0
Breeding: Requires extremely soft acidic water and peat filtration (Atison's Betta SPA works quite well). Precautions should be taken to save the eggs from the parents, which will gladly eat every produced egg. An important part of getting these fish to breed is food, insects, black mosquito larvae and artemia may be necessary to get the females to produce eggs. The eggs will hatch in 24 hours, and will be free swimming 4-5 days later. Large amounts of microfood should be supplied to the fry, which grow slow.

OTHER FISH 1-7
Coral Red Pencilfish aka Nannostomus mortenthaleri
The Coral Red Pencilfish from Peru is certainly among the most exciting new discoveries coming from South America in recent years. It has now been scientifically described as a new species, Nannostomus mortenthaleri (Weitzman & Weitzman 2002)
In the Spring of 2000, the fish was discovered in a collection from the middle to upper Rio Nanay near the town of Albarenga, Peru, by Aquarium Rio Momon, a wild fish export company owned by Austrian collector Martin Mortenthaler. The fish were not particularly common, and only a few hundred were initially caught and exported overseas.
The red pencilfish appears to be a new species belonging to the genus Nannostomus. The fish reaches a length of about 4 cm and only adult males show the deeply red coloration. The sexes are easily distinguished even among juveniles. Males display a white-color pigmentation at the anterior base of the dorsal fin.
The water should be fairly warm (27 °C / 78 °F), be soft and have a pH below 7. The tank should be well planted and the fish should be kept in larger groups to reduce intra-specific agression and fin-nipping. They can be placed together with other small and peaceful fish species, however. The red pencilfish requires a hearty diet of live foods. Prepared foods are also accepted.
Dr. Stanley Weitzman, Curator of Fishes at the Smithonian Institution, has reportedly succeeded in spawing the red pencilfish. They spawned in a 30 gallon tank with Hygrophila on the surface. The water was 78 degrees F, pH 6.6, 20 ppm total hardness.

OTHER FISH 1-8
Puntius dennisonii aka Red Line Torpedo Barb
Common name: Denison barb, Red-lined torpedo barb, Denison's flying fox, Rose line shark, Miss Kerala, Red line torpedo barb, Chorai Kanni, Denisoni barb, Bleeding eye barb, Indian flasher barb.
Scientific name: Puntius (formerly Barbus) denisonii
Synonyms: Puntius denisoni (mis-spelling), Puntius dennisoni (mis-spelling) Barbus denisonii, Labeo denisonii. Some believe that the species should actually be termed Crossocheilus denisonii.
Origin: Endemic to India. Found in Chaliar, Kallada, Chalakkudipuzha, Aralam wildlife sanctuary, Mundakayam, the Kallar river and Travancore hill ranges.
Size: Adults can reach a length of around 12cm/4.5", sometimes slightly larger.
Habitat: Fast-flowing streams and rivers.
Water: This species is found in mountain streams where the temperature ranges from 15-25°C/60-77°F. The pH varies from 6.8-7.8 with hardness ranging from GH 5-25°, making it very adaptable. It is also said to occur in very soft water in slower moving muddy shallows.
Diet: P. denisonii accepts most foods, including flakes, granules, small pellets, as well as frozen foods. Bloodworms, cyclops and daphnia are readily taken and can help heighten the red coloration in the fins and on the flanks. Feeding a color food rich in astaxanthin and other carotenoid pigments as the sole dried food can also help make this species more colorful. Many newly imported fish look very bland, but will soon color-up if offered an appropriate color-enhancing diet.
Aquarium: It's fairly peaceful and non-territorial and can be mixed with most tropical community fish. Keep in a group. Use a tight fitting lid as this fish can be a little jumpy at times.
Breeding: Several males usually chase a ripe female around the aquarium and drive her into vegetation or towards the substrate where she scatters hundreds of eggs.
Rarity rating: An environmental assessment in 2010 listed this species as endangered.

OTHER FISH 1-9
Nannostomus rubrocaudatus aka Purple Pencilfish or Coral Red Pencilfish Type II
The scientific description can be found here http://www.vertebrate-zoology.de/vz59-1/02_Vertebrate_Zoology_59-1_Zarske.pdf
The Coral Red Pencilfish Type II aka Nannostomus rubrocaudatus from Peru is certainly among the most exciting new discoveries coming from South America in recent years. It has now been scientifically described as a new species.
Nannostomus rubrocaudatus sp. n. is described from Peru. The new species is closely related with N. mortenthaleri and N. marginatus. The coloration of the males of N. rubrocaudatus sp. n. in life is extremely different from these species. The new species has a clearly developed sexual dichomatism, which is not to be seen in N. marginatus. The sexual dimorphism in the anal-fin described by WEITZMAN & WEITZMAN (2003) for N. mortenthaleri was also found in N. rubrocaudatus sp. n. and in a “colour variety” of N. marginatus from the Rio Negro basin.
