Well I'm already fully stocked so that won't work (more females or males). It seems with the readdition of the female this barb is now challenging any and all tiger barbs (I have 6) as well now! From what I can see he has established alpha male status in the tank after 1 day with this female in place.
The female's right front fin is all but gone now. I spent about 20 minutes with 2 nets trying to corral the male barb. No luck, as my tank is heavily planted and its near impossible to get the nets around smoothly.
They are now in a faceoff looking at each other with neither moving. Seems like as long as the female can keep her head towards the male he won't advance. As soon as he sneaks up from behind or the side, the nipping and mating attempts start again.
I think I'm going to have to get rid of this male. I'll call my local Petsmart (not where I purchased the fish from) and let them take him. He is a beautiful fish when showing his colors, but I just cannot deal with his aggressiveness in the tank when its already got the aggression from the tiger barbs...
