Stephanie K Posted November 10, 2021 Share Posted November 10, 2021 Hi everyone! I posted a little while ago about some dark spots I found around the walls of my tank towards the top of the water. I received some helpful advice that it could be some kind of algae, but noticed that it’s now on our decor. I’ve checked the dots under a magnifying glass and they do not look like they have legs or seem to move. I can easily remove them from the tank walls with a silicone scraper, but I can’t seem to find any information to confirm what they could be and they seemed to spread pretty quickly. They’re all fairly uniformly sized and don’t seem to break apart at all when I remove them. Tank info: 5 gallon 1 betta 1 nerite snail filtered kept at 79 degrees water is tested weekly Ph 8.0 Ammonia: 0 ppm Nitrite: 0 ppm Nitrate: 5 ppm Thanks everyone, I’d appreciate any help!
