Common name:Borneo Red Fin Silver Shark
Scientific name:Cyclocheilichthys janthochir
Size:20cm (8")
Recommended tank size:180 x 45cm (72 x 18") or larger.
Tank setup:Use rocks, driftwood and robust plants to provide a varied aquascape, and a substrate of soft sand or fine smooth gravel.
Compatibility:Keep in a group of their own kind, as they can display a slightly nervous disposition initially. Peaceful with other fishes.
Temperature:24-28oC (75-82oF)
Water chemistry:Originates from very soft acidic blackwater, but appears to still thrive in more neutral slightly hard tap water.
Feeding:Feeds mainly on aquatic insects and other inverts, so include some live or frozen foods in the diet such as bloodworm, krill, mosquito larvae and artemia (brine shrimp), along with flake, granular and pellet foods, which are readily taken.
Sexing:No obvious differences, mature females are likely to have a heavier body shape, and may be less colourful.
Breeding:No reports of aquarium breeding known.
Comments: Once coloured up, these fish are quite striking in appearance and a group will make a peaceful and more unusual addition to a larger community tank of suitable size. They tend to inhabit the lower levels of the aquarium, so foods that sink fairly quickly are ideal.
