Great small Snakehead, 6" although have seen quotes of 8", not sure if they are true or not.
Very easy to feed, will eat anything, I feed mine pellets, Frozon blood worm, Shrimp, and pieces of whitebait. Live shrimp and worms, they can fit quite alot in there little bellies, He also takes flakes I put in for the Botia's I have in with him.
Yes a Snakehead eating flakes. Some of the shrimp he eats are half his size.
You can keep more than one, they are reasonably peaceful, depends on the size of tank of course.
Get some!
