I've had my little guy for a while now. Best friends with my Sen. Bichir. He used to love bloodworms, but has become more attracted to tilapia, shrimp, and silversides. He's a tough little guy. Held his own against a golden knife twice his size for a while, until I recently separated them.
Definitely under-rated. Not something that grows to monstrous size, but a feisty little fish when it gets confident.
