A fish discovered and hand carried to us from the Kerala mountains, India. This fish does well with two but will do better when four to six are in a large tank ( atleast a 75 gallon tank ). We keep our tank temperature around 78F, PH around 7.0, with a good current flowing through the tank. It has been mentioned that these guys will nip at plants, we haven't seen that in our semi dense plant arrangement. They seem to enjoy the community tank, even shoaling with the Rummy Nose Tetra's . Very hardy fish, with a lot of energy.
