I have a 20 gallon long well established, with 6 CPD's, 6 Black Neon Tetras, and a Blue Florida Crsyfish. This weekend I'll be adding another 6 CPD's, and Black Neon Tetra. I'm removing the crayfish and putting him in his own tank soon. I need two suggestions on more stock.
1. A single or pair of centerpiece fish
2. A clean up crew for this setup/stock
