I have always bought my fish in groups of 6-8 to get a pair, but I have really lost interest in breeding at the moment but would like to keep single specimens. I was wondering those of you who have some experience could tell me if there is anyway to increase the odds of getting a male when they are small? I was thinking of buying the biggest fish in the tank? I know there are no ways of knowing for sure I was just thinking maybe some of you have noticed. i.e when biggest or most aggressive was bought 6/10 times it turned out to be a male. I hope this makes sense anything would be great.
