The primary grazers on my GDA were the common pond snails, which grew about 5 times as big as I have seen before. But, the oto also had a feast. Having only one, he didn't make nearly the big dent in the supply that the snails made. The guppies also spent a lot of time picking off pieces of it. Apparently GDA is a nutritious vegetable treat. The GDA(?) which showed up as green fuzz on the plants disappeared with the GDA on the glass, but I don't know if it was eaten or what. |
