That sux.
Sorry to read that....
Maybe the eel should be moved now that he ate one. The rest are on the menu.
See what this crab did to a gar.

Your above post other and other posts are why I keep my gar with things that are on his menu. NOT the other way around.
Matter of fact I'm taking a pleco down to the LFS this weekend because he has served his purpose. ( tank cycling)
I caught him sucking on the turtles shells so I moved him to the 160.
Now I put some monster amazon swords in there yesterday and he's sucking on them.
I know better then to put him in with Garfield so it's off to the LFS with him.
Gars aren't apex predators, they are in the food chain, not on top of it.
Unless you get a alligator gar.
