So I know my main fish is going to be a large fire eel, ive had a couple before and one of my LFS gets some in usually around 18'' so im going for that to hopefully skip most of the bloodworm stage. I still need to setup filtration and cycle this new tank but just for thought anyone got suggestions on what peaceful options i could do with the eel that will cohabit nicely. plus if anyone has advice on best substrate for fire eel?
