I didn't think that I had any female threadfins out of the group of five that I bought, but I'm starting to wonder otherwise. To help me better determine this, I have a few questions..
Do threadfins often display when they are an all-male group? Mine are displaying like nuts and chasing around two of my smaller threadfins (perhaps the females?). This one pair I had been observing often swim together into a group of stems in the right side of my tank, emerging a few seconds later. WHAT ARE THEY DOING?
Do threadfins color up within days? I got them almost colorless a week ago, and now 3 out of the 5 have fully black extensions and quite a bit of reddening in their anal fins. I know they color up when ready to breed, but I am wondering if they can change so rapidly without breeding. I have a male pair of Longfinned Rosey Barbs, but it took them a month to color up through diet and environment alone. I just wasn't expecting such a quick change.
Two of my theadfins are smaller than the more colorful, larger ones. Their fin extensions are a bit shorter, but not nonexistant. The two smaller ones are also significantly less colorful, but I can also attribute that to their size, youth, and the fact that they have three big brothers to compete with for food. I assumed at first that I had gotten all males because they all had SOME fin extensions and I had read elsewhere that females had none, but if females simply have smaller ones, I might be in luck!
If anyone can direct me to a picture of a typical female rainbow, this would be rather helpful. I'm having a hard time locating a clear photo for comparison.
Just wondering if I got lucky!
