This is interesting... the big rainbow has done something peculiar with the big fantail. He will circle around above the fantail every so often. Either he's asserting his space, or looking to cross breed... only does it with Big Red, doesn't seem to pay attention to the other tank residents. That would be a weird hybrid, brightly colored and obnoxious.
They're both majestic sights. The rest of the darters look so... small. Think I know how that fantail got so big, caught it in the riffles of a large spring that's just packed with these little black shrimp, or something that looks like a shrimp. The darters just love those things. I also found two enormous banded sculpins in the same area, as well as several very large crayfish.
