I have two 55 gallon tanks, one containing a 6 inch red devil, and the other with 4 jds, about 4 inches, 2 firemouths, 1 pleco. I'm planning on getting rid of 1 of the firemouths, 2 of the jacks, and the pleco because he doesn't do a very good job cleaning. I am looking to potentially put an invertebrate or two in each tank to keep things clean... any ideas on what might be a good fit? I have seen some nice blue crayfish at the local fish spot but I know they might be food after a while.
