I put them all in my 90 to see which female would end up with him. Of course, it was the smallest one. She happens to be the meanest one of the three females. She had her jaws locked with one female and was keeping the male and other female under control with her body and tail at the same time. It was funny to watch. I moved the other two females out of the tank and the pair has been digging up everything. Tubes starting coming down Friday and the female's appeared to be all the way down since last night. I still haven't seen any signs that they spawned yet. Hopefully, I'll have a surprise when I get home. The female he's with isn't the female that had laid eggs before. He ripped her face down to the bone while locking jaws with her. I had to separate them. That's why I tried the new approach.
