So last weekend I had bought 2 pairs of guppies. The guy from my LFS seemed 100% sure they would provide fry, and he was correct. So far, I count 5 and have only safely gotten 2 into a breeders nest. Now, I’ve had 1 male and 1 female each die… my question is, is this normal? Do several pairs do well together or does it actually become about mating, protection, claiming a female as your own, etc… Not sure if fish are this sophisticated. Water parameters are good, WC done yesterday. I want to believe that having 1 male and 2 females remaining wasn’t ideal? When the first male went, I saw the other 3 were pretty much teaming up on him… I didn’t see if they did this to the female that just died. Any knowledge would be appreciated.
Guppies don’t just die. Granted they are a short lived species but you should be getting two years out of your fish. Most of the guppies I have bought from shops have had internal issues and needed and good dose of General cure. A lot of times the swelling caused by these issues are missed and everyone just thinks the fish is pregnant.
Male guppies will often chase a female to death trying to breed with her. Some males will attack and kill a perceived “weak” male. At least two females to every male is recommended. Those guys are all about breeding. Most guppies come with parasites API has a good medication for it. I’ve gotten anywhere from two to thirty fry from a single female. And if you mix males and females, they will NEVER stop having fry.
