The new one is a 10 gallon tank. I want to eventually get a 20 but this one is free and is bigger than the 5 gallon. Im going to put the adults in the 10 gallon and move the fry to the 5 gallon as suggested. Im going to move the 5 gallon into my daughters room since I think it would be perfect for her to experience this.. Even though she is 4 its never to early to get her interested in things. Everything is with the tank. It used to be my grandfathers and he gave my sister the tank so he could get a bigger tank at his house. These mollies seem very strong so Im going to try a fishy cycle so that I can get those fry out of the bowl and into some warm water. I will however run the new tank for 48 hours. Will that be ok.
