freshwater eels?

[guppy]

What about Aethiomastacembelus shiranus

since they are a few inches shorter as adults than adult fronts and so narrow bodied I would worry that they would be considered snack food.

Better stick to something bigger, IMO.

if you can try and get a larger one
but i would get a fire eel or a tire track eel

Why not get one of the Tanganyikan eels? Frontosas are Tanganyikan, so you could stay in the lake that way.

I was going to suggest this, too. This would probably be the best option for compatibility and a natural look.

Why not trying a swamp eel, Synbranchus marmoratus? They get big, but not to become a threat to the fronts, are hardy and peaceful. Look at mine:



Do you like its smile?

Best regards.
