I have a heavily planted 55G Discus tank with 5 3-5" Discus. I had some Spotted Corys that seemed to be suffering in the discus heat...83-85*, so I moved them to another tank. What would be your recommendations for some bottom feeders and an algae crew. By no means do I have an algae problem, but there would be some good food for an algae crew. Tank parameters: NH3-0, No2-0, No3 ~10, pH - 7.2, KH-10, Co2 tank injected. Thanks.
