spiny eels?

Question

they burrow right in a gravel sustrate? Also are they community or agressive

Answer 1

Many of the species are burrowers, and you could keep them with fish big enough that they can't be swallowed (also nothing large and aggressive enough to eat them!). You can get an idea of what can be kept with them from the community lists in this link: http://www.elmersaquarium.com/10eel_peacock.htm
