As opposed to keeping fish in a glass box?You shouldn't separate the sexes. It is common advice here, but it doesn't respect the natural behavior of the fish. It controls them for our needs and disregards theirs...
Gadfly - I see your point, but we can also see different behaviors inside those glass boxes, if we plan them right. You can see guppies being splashes of colour, and you can see behavior not much different than what I've seen watching livebearers in the wild. I'll take interesting behavior every time. Social fish with no society aren't the best aquariums.As opposed to keeping fish in a glass box?
I would advise gathering as much advice as possible and then going by what works for you. Separate the sexes, cull them, or get a predator if you can’t get rid of them fast enough.
I see no confrontation going either way in the postings. Gadfly has a good point there.Let's not start anything here. There's no reason to be confrontation even if we disagree.
If the tank is 45 gallons you have some room for fry-eating fish. Most tetras will eat fry, as will barbs, as was previously mentioned. You could also do a single male swordtail, if your platy is a male as well.I don’t want to have another 45 gallon tank with 50 fish between the two of them. If they all survive the tank won’t be able to sustain the life of all the fish. I was hoping PetSmart would take them but they won’t. I know this sounds bad but I’m hoping the adult guppies eat the new babies. I was fine with the 13 guppies who are growing and the 2 adults and 1 platy but now the tank only being 45 gallons I’m gonna be in trouble lol
