Tanganyikan Eel - Red Gills + Bottom

I think it would depend on the species. Some stay small and some get bigger. I think yours is a Mastacembelus tanganicae, which is one of the smaller types meaning a front would eat him. I have seen larger species like elipsifers kept with fronts and it seemed to work. It would be a rick though.

This is the most recent picture of my eel. He's slowed down growing and has started filling out. Most interesting fish I have ever owned.

Here's an older picture of when he was about 6" long
