Welpl, I tell ya, if he was undernourished, he was very big and healthy for a fish he wasn't supposed to be eating.
In my Aggressive tank I had a Snowflake Eel, Spotted Grouper, Porcupine Puffer and a Lion Fish, all ate the same thing. Had em for 2 years, and man did they get BIG. Anyways the reason I don't have them is they got to big for the 125 I had them in. Coulda kept a couple but decided I wanted to go with Tangs instead.
