Aggressive male guppy

    Recently I noticed my male guppies nipping at me females fins. Their tails are kinda busted so I removed the females from the tank. It's been 3 months since I bought them. Anyone know any reason for such sudden aggression? I've had about 3 batches of fry. The ratio was 3 males to 8 females.

    Ammonia 0
    Nitrite 0
    Nitrate 10
    pH 7.2
    Temp 75 F

    Anyone know if I would be able to reintroduce the females ever?

    It's probably just breeding behavior, with the males getting a bit too insistent.

    What size tank?

    The tank they were in was 65 gallons

    The females are now in a 20 with some Corydoras

    So it's likely not because they're cramped in a tank size that big. It's likely breeding persistence. Males can be rough!

    Should I leave the females with the corys or should I reintroduce them after a while

    I'd leave them with the cories if you're breeding for a specific purpose. No reason to put the them through the stress of harassment, breeding, gestation, and birth if you're not specifically wanting the fry.
