Since I want my Oto to get the most nutrition, I bought some Algae Wafers. The man at my lfs said that the AW would be too big for my Oto, so he suggested that I break them into 1/4s. That night, I did and 4 days later, my tank water is green. I don't see excessive algae growth except for the water (which I don't care that it's green, not necessarily unhealthy for the tank if controlled) and my Oto seems to be enjoying the algae. My other fish don't seem affected, but I still have a question. Why is it that an algal bloom appeared shortly after I put in the 1/4 bit of Algae Wafer??
