I have had my betta for 18 months in the same tank, 24 x 18 x 18 inch. There is a heater and air bubble filter and it was well planted until recently. A bright green algae seems to be taking over the tank! It grows on the glass, the heater, the filter and on the gravel at an alarming rate. Seriously, this stuff takes over the gravel within a week. It is thick, bright and grows like crazy!
Will it hurt my betta?
I keep scraping it off the glass and other things and scooping up the gravel that is covered with it, but it comes back. There is hardly any gravel left in the tank now! I threw out all the plants because they were covered with it. I replaced the fluoro light with a new one. The heater is set at 24 c. There is no direct sun hitting the tank. It's as if an algae invasion dropped out of the sky and hit his tank!
I would like to go back to a nice, well planted little home for my boy, not an algae covered icky mess. It is mainly the thick carpet of algae on the gravel that worries me. Any thoughts anyone?
Thank you in advance for your help.
