I'm in the process of setting up a new 55gal tank. All I have is onyx sand and lace rock. I'm going to add plants soon and probably more rock. I've went from wanting S.Am dwarf tank to rift lake cichlids! I love live plants and want an interesting mix of colorful fish. So, I thought about having some p.pulchers (or some type of w.af. krib), dwarf african butterflies, congo tetras and diamond tetras. Not sure about how many of each...still researching. Any suggestions welcome. Also, any suggestions about bottom feeders...I want to find an african cat that won't get huge!
