I was planing on having 3-4 platys or swordtails in my community tank. With other small community fish such as Dwarf Gouramies, Tetras, Barbs, Corys, Danios, etc . Will the livebearers reproduce?. And will any fry survive to overpopulate the tank?
Simle answer yeah- my female platy is as fat as a barrel as we speak. Not had her long, so I've no idea what the chances of the fry surviving are. My best guess is they've got 2 chances- slim and none
yes they definetely will, they are probably pregnant from the shop and yes to the 2nd question, then if you don't rehome them your tank will be full of inbreds
Yes, they'll certainly breed. But with those companions, my hunch is that you will only get the occasional survivor and that only if the tank is heavily planted.
