If I'm not mistaken, that bass is gonna eat anything it can fit in his mouth when he gets bigger. Will likely eat the firefish first. I know you've heard enuf already, but you really need to do better with fish choices - on the compatability and amount in the smaller tank areas. I know I got real excitd when I first started keeping SW fish too, so I can "kinda" understand what you're going thru. I just hope it's not too painful a lesson for you.
