I noticed you said you were having trouble with your 4th female getting her to breed due to her size and fending off the male more so than your others. I am having the same problem with my Royal Marble Pair. My male is an active breeder but she is of similar size and just doesnt want to give in to him. Any suggestions on how to get my female to become a more frequent breeder and give in to him more? Any suggestions are appreciated. Thanks
