I've kept all of these except the C. macracanthus, but a real good buddy of mine had them for years and I loved watching them while we were hanging out at his place. They are one of the fish I want to keep at some point in my life.
Sorry, no prob. The first is an L046, zebra pleco, the 2nd is an orange zebra otto, 3rd is an L450 pleco, 4th is an L240 pleco, 5th is a sid (botoi sidthimunki, I believe), the 6th is a FW flounder, and the last is a sewellia lineola loach, that are breeding like crazy in my community tank.
