Fishysweet- the cichlids in your tank don't grieve the eel?
I've come into a couple of tiny jaguars that are currently in grow-out, and am thinking of putting them into the 100Gal as they get big enough to not get consumed (local eel as well as nasty black mullet & big-mouth sleeper goby, all with mouths about the same size).... under much and careful observation, certainly.
