1. Didn't you just buy that Flowerhorn? No way it would have paired and bred this quick.
2. Kamfa have a higher sterility rate
3. 80-84F is fine for them. 75F is far too cold, ignore that post.
4. Do you even know if the BP is female? It could just be overfed/constipated.
5. The Flowerhorn is probably too young to breed.
