i myself dont like the redtails. they dont have that true cuda look. the red tail cuda eat fine. and he was a tuff fish. took quite a beating from the wolf and lived. but they are very skittish. easy to take care of as well
the yellow cuda is the cool looking one. slim , slender lots of teeth, more a true cuda. and are harder to keep alive though, need a long tank since they like to take off for there prey and hit em hard and fast . love the yellow tails.
