I recently purchased a 3 gallon tank for my betta fish, Tater. Tater enjoys the space he gets in the tank as well as the numerous plants the tank contains. However, with the introduction of a new plant into the tank, I inadvertently introduced algae as well. The algae is really starting to take over and is on the glass and rocks of the tank.
Never having been a fan of chemical algicides, I decided to take a natural approach. I purchased a tiny plecostamus catfish to clean my tank (only temporarily, mind you, because I understand that they get quite large).
I picked a plecostamus because I've heard that even bettas are able to get along with that type of fish. Such was not the case with Tater. He chased the catfish all over the tank and stalked it down like some sort of prey. Now I have Tater seperated into another tank until such time as I can transfer the catfish to my brother's larger freshwater tank.
My problem is that I still need a solution to the algae. I do 25 percent water changes weekly, and I never feed my fish too much food. The tank has a filter, too. And yet, the algae is everywhere. In spite of water changes and tank cleanings, it still comes back (and with a vengeance). I need a fix to the algae problem and was hoping you guys might have a suggestion on a natural approach.
