Freshwater Aquarium/water-change


Hi...its Veer(hope u remember me ;), white molly has given birth to 30 to 40 fry.
the fry were born in a tumbler (which has plenty of space for the fry).
I've decided to have a daily water change of about 75%.
IS it ok?

Hi Veer

No, a 75% daily water change is too much. You can do 30% water change once a week, then a 10% water change about mid-week. If your water parameters are high, your tank may be overcrowded. Consider moving the fry to a larger tank of their own.

Hope this helps, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.


Many years of personal experience with community tank fish, semi-aggressive fish (Barbs, Tetras, etc), Angels, South American Cichlids and African Cichlids.
