I have a 180 gallon tank with those fishes in it, just those. i wanted them to breed but the female dies when she is giving birth??? how? the temperature of water is 78 degrees, and the water has no nitrate amonia is good, tested everything, it all good. is the female just stressed or something? it has lots of plants to hide in and stuff, i dont think i should put guppy in breeding box, but if i do will it give better chance of keeping mom a live? plz help
