Here is my 8 gallon mantis shrimp biocube. It has VERY weak led lighting but so far it can support mushrooms and macroalgae. It contains, discus mushrooms, blue ochtodes, flame algae, fire fern, large feather duster, hermit crabs and of course my mantis shrimp. So far the mushrooms aren't stretching for light and the macro is growing but according to my lux meter I'm getting very low par from these lights. I'm looking for suggestions for interesting inhabitants. Not really looking to add corals other than my mushrooms but something else oddball that isn't too tough to care for. Anything you think might be interesting that doesn't need a lot of light and I don't have to feed 3 times a day. Not planning on adding any fish. Thanks for any suggestions.
