Molly Barrel Rolling

[tophat110]

I started a 29 gallon tank on dec. 4, 2010 and had only three molly's, two have died and the thrid on is swimming on its side and is barrel rolling. I am not sure what is going on. Anyone able to help. If this one dies what would any suggest to do to with getting new fish. Thank you in advance.

Go to the new freshwater tank section on this forum and read beginner's resources noted at the top of the page. My best guess is that your tank did not cycle and that you have or had ammonia and nitrite build up that eventually killed the fish. Read up on the fishless cycle so you can get this tank in order. And you can. You just need more knowledge right now. In the mean time, rush now to do a 90% water change and do one of these every day until you understand cycling. Not sure if you can save your fish but BIG water changes will be the only way.
