Freshwater Aquarium/white fuzz on aquarium stones


Hi Jaymie, I recently set up a Hagan fluval edge 6 gl tank (about 2 weeks) No fish yet but all my plants. I've noticed a white fuzz starting to stick to the stones looks like fuzz.. I'm attaching a pic.. any help is appreciated... Carl

It sounds like you have algae in the tank. This could happen if you seed your tank with fish food, overfeed fish in the tank, or the aquarium light is left on for long periods of time, or the aquarium is next to a window. Since there are no fish in the tank I will assume it is probably due to overuse of light. I would suggest removing the rocks, cleaning them off, and put them back in. Do not leave the aquarium light on for more than eight hours a day. If the aquarium is next to a window I would suggest moving it. I would also make sure that the filter is working properly. If your aquarium light is not on and the aquarium is not near a window let me know and I can try to figure out why the algae is growing in your tank.

I can answer question regarding, raising, breeding, feeding and the general upkeep of Betta fish. I can answer general questions about isolating a disease and the treatment needed to help your Betta. I am knowledgeable in fresh water tanks and can answer any question regarding them. I cannot answer questions about salt water tanks.


I have had fresh water aquariums for most of my life, including the 23 years I served in the Marine Corps. I have been raising Betta's for some time now, and have ventured into breeding a few years back. I currently own 5 males and 4 females and I have about 200 almost 3 week old fry. I make my own filters and I have tried almost all the food on the market for fry and I know what has worked for me and what has not worked.

I do not have Betta related educational credentials, but I have educated myself in Betta care. I have read quite a few books and articles from both the internet and ones that I have purchased. I consider myself well educated in Betta care.
