I am in the process of planning an upgrade from a 75g mixed reef to a 120g mixed. I am interested in getting a dwarf golden eel and was wondering how i should cover the tank. I have the 1/2" clear mesh screening on my 75g and was thinking the 1/4" clear mesh from BRS for the 120g. They say the average thickness of the eel is a pencil which is right around 1/4". Does anyone else have experience with these little guys and use mesh as opposed to the glass tops?
