I hope I am not commandeering this board with all of my questions! I have been looking into C. borleyi redfin, and saw some at a LFS. All of the fish were young and did not have full color but they seemed to show some hints of orangey-red on the body and bluish heads. Does this mean categorically that they are all male? The guy at the store had no idea but said I could vent them if I wanted to buy them.
Also, I have seen it mentioned in one or two places online that venting is horrible and cruel for fish, and should not be done. I have vented my fish when rehoming them, and I keep them underwater and only briefly hold them in the net to check them. They don't seem worse for the wear... but then fish don't have therapists, either! lol... Am I abusing my fish without knowing it?
Thanks for all of the excellent advice!!!
