Hi, My brother-in-law has a pair of convicts and decided to bring me two baby fry. Well he drove 3 hours with them in a fish bowl with about three inches of water and about two dozen gravel bits. He even left them in the car while he went into his grampa's house. When he handed me the bowl I could feel heat coming from the water. I had no idea that they were coming but I had a recent batch of platy fry and so I put them in their tank. The little guys couldn't even really swim the first two day. I am guessing they had just hatched! Now nearly a week later both of them are free swimming and eating. I just can't believe they made it! I doubt the ones left in the tank did. (he has more than the mating couple of convicts.) A three hour car ride, and trust me my brother-in-law's driving is enough to scare you when your buckled in! LOL. I just thought I would share this story because I just can't believe it! How long do you think they can stay with the platy?
