i had 3 channels but one passed so now i have a 5'' albino channel cat, 8.5'' normal channel cat (i dont like calling them blue channels because only the males are blue and it reminds of the Blue cat x Channel cat hybrid) and a 9'' Lima Shovelnose and i feed the frozen bloodworms with the occasional rosey reds. Ever since i jacked the temp. in my tank to suit the Lima Shovelnose which was 4 months ago my normal channel cat chases my albino really fast and nipps his fins. He is very agressive and chases and eats any live food put in tank immediately even with lights on.
