A considerable amount of algae (patchy and brownish) is starting to appear on the inorganic surfaces in my community tank, which has been running for about five weeks.
This 20-gallon high
tank contains gravel substrate, some smooth river stones, one live banana plant, several artificial plants, and a resin decoration. The hood lamp is a single-bulb 17W fluorescent, which is illuminating the tank about 10hrs per day.
The algae are colonizing the artificial plants as well as a resin decoration. Nothing visible on the banana plant.
I'm looking for suggestions on how to eliminate the growth I can see and control future growth.
The tank is stocked with Red Phantom Tetras and Zebra Danios. I was planning to install additional live plants. I'm thinking small scale, for now, using something that thrives in moderate light. Java Fern?
I had also been hoping to add a bottom dweller to the tank, in order to add some energy at that level and do a bit of substrate clean-up. I was thinking some kind of Cory Cat. I didn't intend specifically to have an algae eating fish down there, but now it seems I need to rethink the whole balancing act.
So where should I start? Plant? Snail? Shrimp? Fish?
