So I am working on setting up a tank for an American eel, and as the species is not commonly kept in aquariums, its a bit tricky to find information on how to keep them.
Anyway, I have read that eels like to burrow and hide, and I assume this is the same for the American. I have heard that eels can be "dirty" so I have been thinking about forgoing substrate all together to keep the tank cleaner. In order to accommodate their desire to hide, I would build a series of rock structures and caves for him to hide in.
So I guess my question is: is this a good idea, or is substrate going to be a must?
Any other tips people can give me for keeping these guys would be appreciated as well.
