These fry are between a few days and 2 weeks old. I have several batches in the 5 gallon tank right now. Most are guppies, but 1 is a variatus? and one looks like a dalmation molly. What I have them in has a filter which I covered with a mesh bag and use an airline hose to do a water change once or twice weekly 25%.
If I put them in the 10 gallon tank, I will have to buy a filter for it, which isn't a problem, but what would be the best filter to get? I have plenty of mesh bags I can put over the filter intake tube, and can add the filter pad from the 5. The 5 is a hex tank and the filter won't work on the 10 gallon.
