Can Gourami Change Gender?
Hi guys, I've seven female gourami living together in a large tank for a few months now without any issue. I started noticing the fins on one Opaline gourami becoming longer a few weeks ago and three days ago she went into a cave a refused to come out until today. However, the fish who came out of the cave looks very, very male. Her top fin is now long and pointed where it used to be rounder and shorter. Ever since she/he came out of the cave, the other gourami have been hiding and a bit aggresive.
I'm considering taking this one back to the aquarium. Do the males come into their pointed shape later in life? Or if it was a female who changed to a male, if I return it, is it likely one of the other gourami will start changing into a male as well?
Thanks for any advice you can give me. ^_^
