Mine are doing good too. Some blew up and are large and goregeous, others are still small. My biggest one was trying to take on a regular texas 1/3 bigger than him earlier!
I have mine in with fish that are over 3X it's size..A 7" GT, 8" Carpintis, 5" Firemouth and a couple of Convicts..Little guy is about 2 1/2" now and is always in the mix w/the bigger fish for food and attention. Now all you need to do is start breeding them FH's.
thats why I got him buddie!!!!! Going to breed him with mom to bring out big head and pearl type of RT. Also, they will throw off some awesome Faders as well!!!
