I want to set-up a saltwater eel tank. I have a 55 gallon I'm going to use and I have done some research and there are a few that would work well in this size tank. I want to do live sand and live rock maybe a few hard corals in it. I dont know how ever if this will work with eels. This will be my first time with true eels and I want to get as much information before I begin. So if you know if this will work or not let me know. Maybe some good corals if it will. Also if you have any suggestions on the type of eel. Last thing is I have read in multiple places eels like to have a companion, if so let me know. Thanks everyone.
