Yes, during breeding, Jewels have no regard for fish size and will go after anything in the tank. If you wish them to breed, I would have them in a separate tank (no smaller than a 3ft) so they can have some alone time.
Excellent, thank again guys... very helpfull think I will re-home the female. Sorry for the annoying questions, but if I was to get an other male, would they just fight or could they get along? It's a big enough tank, 2ft tall 2+1/2ft deep corner tank.
