Here is one of the baby silver mollies in my live bearer tank. It is a 20g tank with mollies and guppies. All are prolific breeders. I currently have five adult guppies and eight adult mollies. There are about 60 fry ranging from new born to six months. My LFS has been taking the mollies in trade for plants and feeders for my Red Devil, and I thin the fry out as feeders periodically as well.

I know that the tank could be considered over stocked, but I keep very close tabs on my parameters. With weekly 25% changes, I maintain 0-.25 ammonia, 0 nitrIte, and 10-20 nitrAte. My water sprite and java moss have been doing their job. My pH, as you can imagine is pretty low for mollies and guppies. It usually sits around 6.5. I have thought about raising it, and the hardness, but the fish are doing very well, so I haven't messed with it. Why fix something that isn't broken?

Anyway, here is one of my babies. The picture isn't the best as the shadow from the shell cuts across the molly. Its brilliant silver is not done justice.

edit: Just thought I would add...I have a blue and red female beta in the tank, and she loves it.

Mollies and Guppies are very popular aquarium fish because they can endure all kinds of conditions that aquariumists throw at them. An ideal ph for these fish would be 7.5+ but, as you have found out, they they do great at 6.5. Your Ammonia is up probaly because you have too many little fish in the tank. Keep your water clean and with plenty of filtration and your fish should trive.

coooool! great pic too

Yeah, the entire aquarium, except for my male dalmation sailfin and female beta started as fry, and I have at least three generations of both mollies and guppies in the tank.

The parameters have remained pretty constant for a couple years now. A while ago, I tried upping the pH and hardness slowly over the course of a month, but after a couple of weeks, the pH was around 7.5 and my sailfin started pineconing, so I let things go back into its own balance, and have not had any problems since. The sailfin slowly got better, and is fine now.

Knock on wood, but I have not had any illness, and as you can see in the picture, the glass is clean. I have never had any algae issues. If the amonia hits .25, I do an extra 25% water change that week.
