Once and a while I come across a aggressive male in a spawn that looks like it could be a good candidate until it severely wounds or kills a female. Normally I can avoided this by breeding a brother in the same spawn but now I am stuck I ended up with one male from my last multi spawn and he happens to be a slight psychopath. I have tried breeding him like the rest of my males in a 5 gal container shoved full of java moss and oak leaves. Males are conditioned in 1/2 gal containers on frozen bloodworms, pellets and live black worms for 1-2 weeks. Females are always in condition in the tank but moved to a secluded half gal for 3 days before spawning. Here is the male that is causing this post... he is 5 months old not much to look at but I promise he has good genes hiding in him . I have tried spawning to his sister and 2 other females (thinking maybe he didnt want to spawn to that girl) but he will beat up all of them until I remove them. He is a massive bubble nest builder they stick out of the water and inch. He recently attempted to spawn and he got one embrace then chased her off violently. Am I doomed to never breed him? Is it his age or should I try a larger container?
