have thought about a lion, but had a little concern about putting one with the triggers. although for the time being, neither one has displayed any sort of aggression, i've heard horror stories of fin nipping. plus, my first fish was a lion, he was about 3", he acclimated well to the tank, ate live food like a hog. i tried to ween him off of the live food (tried almost everything, garlic additives, feeder stick, different foods) but nothing seemed to be working. So, I tried to let him go for a little while without any, in the hopes that he would take the frozen. He didn't, and he became extremely slow and sedentary. I believe it was at this point, I don't have any proof, because he disappeared, that I think he was caught and eaten by a medium sized strawberry hermit crab. So long story short, I'm a little wary of trying a lion again.
