I am in the process of building a plywood FOWLR tank, the tank will be 100-120 gallons, I was thinking of stocking it with 2 snowflake eels, a lionfish, and 2 triggers still unsure what kind. Is this possible ? I will be putting a maze of pvc tunnels under the rock for the eels, would they get along in this size of tank for the life of these eels and fishes??? Will be using a HOB filter, protien skimmer, and something for water current in the tank. Had some nightmares with sumps so am trying to avoid them if at all possible. Any advise would be greately appreciated.
