Everything I seem to be able to find on Uaru says they are fast growing. But mine has only grown to about 5in. in about 10 months. He's active and seems to eat all right, but he only seems to grow about as fast as my Dempsey. Is this normal? Which leads me to question two. I've been feeding him a mix of romaine lettuce, spinach, Hikari Bio-Gold+ pellets, bits of shrimp, and the occasional mealworm. Is there something better I could be feeding him to give him a healthier diet? He's in a 180gal tank with a 50gal sump(30gal of water.) His tankmates are a pretty docile Oscar, a Dempsey, a female Convict, and five Silver Dollars. There are no signs of fighting between any of the fish. Any advice would be appreciated. Thanks!
