Killer in my tank

[youtoo54]

180g tank FOWLR
Small snow flake eel
dog face puffer (missing a fin on his left side)
lion fish fuzzy (RIP)
lion fish volitol (RIP)
fox face rabbit fish
tomatoe clown x 2
coral catfish
lunar wrasse

This is whats in there. Ive had a couple tangs die and I thought maybe it was stressed related but maybe not now. Fuzzy lion was killed first and the guy at petco said when I bought him he was a 50/50. The other lion fish was doing great for about a month+ now and went MIA yesterday. I found him today half eaten! Now ive noticed my puffer is missing a fin. WTF!! Think its the eel? Hes the only one that doesnt come out and "hang" out with the other fishies.

Could be the eel or the catfish. They are listed as aggressive on LiveAquaria, but I don't know how aggressive that may be. If your eel is much smaller, I would look to the catfish as the culprit. Alternatively, you may have an evil hitchhiker on your LR.....

I'm willing to bet the catfish is the aggressor...they only get worse as they get older and larger.
