I have a peacock eel that is getting beat up in my 150 so im moving it to the 55 as soon as the piranha goes. I want to replace it with a bigger eel and I looking at a fire eel. i'll get one at least 10-12" but im looking a the road ahead. I know nothing on their behavior, feeding habits and aggression. I have a number of african cichlids ranging from 2-6" and loaches (clowns, yoyos, and borders) ranging from 2-5" and a few snails. With this eel eventually eat or kill my other fish?
