They are mainly photosynthetic.
But you can spot feed them from time to time.
They will eat any meaty foods your fish will.
Krill, mysis, clams, shrimp, steak, lobster.
Just kidding on the steak part. No cow.
But like I said, most photosynthetic. The spot feeding is just a bonus.
Beware, they will eventually get really big.
What kind of condition is he is now? Any pics?
Alot of the pet stores sell really stressed, pale, white sebaes.
They go through alot to get to us.
