I myself never saw him do it, but my boyfriend caught him on his way to the crab tank, and put him back in his own tank. I don't know if he would have gone back to his own or just stayed in the crab tank and had a king's feast. I'm going to guess feast!

The clown fish he ate was in his own tank. Maybe he didn't get fed soon enough and went for a fellow resident.

We had a bunch of other really cool fish too. I had a cow fish and a brittle star fish. The cow fish ate all the legs off the brittle star until it was left a stump. Still, it managed to survive without legs for quite some time. Oh, and I had a snowflake eel too. Ah, the good old days.

Here's a cow fish. Mine started out as a "dingleberry" (seriously, that's what they are called as babies), no horns, and about the size of a sugar cube!
