I have 2 texas cichlids in a 180 with 2 jacks, an oscar, and a royal pleco. They are prob only about 4 inches at this point and yes, they are growing slow. They have completely stopped coming to the surface for feedings so I've resorted to sinking pellets etc. They are never too excited for food. I get the impression they prefer to forage around while digging through the substrate. Of course I'm concerned they aren't getting enough food. They seem to like peas and blood worms as well but still won't aggressively go after anything. Considering cutting to once a day feeding but I was goping for sone quicker growth. I really would like to stick with pellets as a base and then provide other treats. Just interested in hearing what others are doing. Thanks.
