At this point, I think these guys are too big to rehome.I can totally understand this, I might have tried to find new homes for them and put something else in the tank.
On a different note, Do you think you can breed these brutes in a tank ???
As far as breeding them, I'm not looking forward to that. The tank is way too small and too much work. I like to just grow fish out. It's about 20 months for these guys so far.
