Nice! Yeah the dat is not pellet trained yet. Still working on it. He seems to enjoy watching them sink but has absolutely no interest in taking them. So far he's taken bloodworms and ghost shrimp along with the occasional guppy. I had the bright idea of dumping 60 .5" endlers in the tank a while back to liven up the top and give my more aggressive fish something to chase... so far not my best decision. sounds like I need another half a dozen or so poly's. Mostly just ropefish, delhezi and ornates with an occasional endli around here but I'd be fine with a pile of them in my tank.
Mine is WC and has grown about an inch per month - I've only had her since December. She started at 6 inches, and supposedly will slow down now at this point. I fed once daily when I first got her, now I feed about 4-5 days per week. Silversides, catfish, frozen krill, pellets, and occasional live earthworms.
