Can black mollies live in a ten gallon tank? The people at Petsmart said they could but I wanted to be sure. We have a ten gallon tank with a hood, light, and filter but I was wondering if they need a heater as well. I am having trouble finding info on these fish and their care so any advice is greatly appreciated. Also, can a 10 gallon tank be cycled?
10 gallon tank... ok for black molly?

I'm surprised you can't find much info on this fish, as it's one of the most commonly kept fish in aquaria. I suppose they could be kept in a 10g, but because of their size and prolificness, I'd suggest that they be kept in something larger.
Black mollies are cool looking fish. I have been thinking about getting some. From what I have read they aren't a starter fish and are somewhat harder to keep. The 10 Gallon seems a bit small seeing as they grow to about 3" in length. I have seen a min of 20-30 gal suggested but depending on the number you want to keep in your 10 you might be able to get away with it. As for the heater it really depends on what your water temp is and how much it changes. Black mollies can take temps from 68-82°F from the reading I have been doing. If your tank stays somewhere in there without to much change you should be fine however you may need to acclimitize them if the tank at the store is a lot warmer then yours. Anyways have fun and if you do get some I would love to see some pictures.
You might be able to go with just 2 males, that way no babies in the future. Of all the fish I have had, mollies are the ones that usually come with diseases. Never fails, they come and look healthy. Within days the pre-existing tankmate mollies get sick ( ich, etc.,)and then die. The new mollies also end up getting sick and dieing. Don't know why. I don't want to introdue any to my big tank for that reason.
