I bought a tank and filter for a ridiculous price a few months back, but there was a catch. I had to take the fish that were in the tank. I have identified all the fish but one. This hybrid, which I assume it is, eludes me. When I got it, the fish was silvery gray, but is now showing some impressive colour.
I was wondering if anyone has an idea what species it may have come from. This fish is in a tank where no fry will be distributed, so there is no issue there.
