bro, you paid $54 for it?
it's all good though, you can't go wrong with citrinellus.
i feed mine silversides, mysis, hikari bio gold and sometimes if he's lucky i'll throw in a crap load of blood worms.
mysis and hikari are probably the best things you can feed him.
prawns are lovely to.
i remember when i got my citrinellus, for my birthday.
he was only like 3" then, now he's 12.5" or something like that.
got him in grade 10, grade 12 baby, he's all alone in his 125 gallon.
tank might be tight for him, but it's good to have a wet pet in your room.
just turn on his light at night and watch him bite the glass mang.
