4-5cm Scissortail Rasbora. Latin Name: Rasbora Trilineata Water quality: 20-25°C, pH 5-7 Compatability: They make an excellent fish for a community tank and can be kept with a large range of tropical fish. Diet: Small frozen foods such as mini-bloodworm, white mosquito larvae, cyclops, baby brineshrimp, and daphnia, plus crushed flake and micropellets. It is a gregarious species by nature and really should be kept in a group of at least six to get the best out of it in the aquarium. The fish show better colours in the presence of conspecifics, are less nervous and the display on the whole is far more natural-looking.
