Many months back, I had a disaster in my 45 gallon tank. A heater went bad on me, overheating the tank, I lost everything inside. The plants survived and the snails survived (go figure). I loved the tank, planted with turquoise rainbow fish and a chocolate pleco. I let this tank run with nothing more than a yoyo loach which I moved from another tank. My kids have been giving me grief about this tank for awhile now. But money is tight and replacing with more expensive fish (like I wanted) wasn't an option. So I headed off to a big box store about a week ago and came home with 15 mollies. 5 each of orange, black, and long fin. I haven't lost a single fish. And this tank has never looked better. I did a few small doses of meds just in case, but mostly just added them to the tank. The plants are starting to look awesome...bright and green!! These little guys have cleaned off most of the algae. For a fish that I wouldn't have given a first thought to a year ago, I sure do love these little guys. It was a heartbreak for me when that tank went down, but I've been enjoying it so much this week.
