I'm setting up a 55 gallon FOWLR tank. So far all there is, is the tank, heater, Fluval 306 and some water.. lol. A long way to go I know. Anyway. I have a few questions on future tank mates. I already know that I will be getting a dwarf zebra/lionfish. I have always wanted one and I'm setting the tank up specifically for my little buddy when I finally get him/her. I'm doing FOWLR as I mentioned with a deep (4") substrate. Now, I know the dwarf lion is a small fish 6-7" grown, so I need to find a few suitable tank mates. I really don't want large fish (space for the grown fish and bio-load). Any suggestions?? I would like to keep some maintenance inverts but I don't want them eaten either. Advice?? Long term after the tank is established for a while I want a green or red mandarin. Is this a good idea at all?? I know the lion is a night hunter and the mandarin is a day hunter.. If I provided the mandarin something like a cichlid <sp> cave for hiding and sleeping would it make a difference?? I'm just looking for ideas and help from the forum on this.
