i have peppermint,commons and albinos and orange spots thay have bred once or twice but now thay wont ive done water changes played around with the temps feed them well ive ran out of idea's can someone give me some info
Separate them into species only tanks to prevent crossbreeding.
Take photos and sex them. Too many males can disrupt breeding.
Keep up the water changes even if its only 10% every second day.
I agree with Brengun, tell us more about the set up, how mant tanks, how big, how many of each fish and what sex etc.
dont give up -it maybe you just need to have them organised differently.
