a while ago i was asking if anyone new what type of fish i had. i thought it was either a red tail botia loach or a redtail shark. i came to realize that it was a rainbow shark. and i also found out that they can only be housed singally in the aquarium. i was always wondering why they were fighting. well after my fish were sick from the addition of a lfs's fish, and i cured it. they had ich and cloudy eye. my one shark is now blind, he doesnt even have eyes. well, now the other nows it and picks on him a lot. so today i tried to put the blind one in my 20gal that just recently finished cycling, and he hated it. he kept trying to jump out. so i put him back in the 55gal, and hope he is as tough as he thinks he is.
