Ok, Ok!!! I know this is bad but I can not figure it out so I'll break the guy rule and ask for help. I have a 55 gallon planted tank with guppies in it 2males 4 females, along with a male and female platty and my pleco. They have been in the tank for about 3 months and all the fish are doing fine. My problem is I can't get them to breed. All my females are huge with gravid spots, but I'm getting no fry. I tried using a net breeder to see if I was just missing them and the were eating the young but after a week I releassed the female back in the tank. I have resorted to also adding breeding grass to the tank, but still nothing. If anyone has an idea on what I may be missing I would greatly appreciate it.
