Anyways, I think I brought in a few fruit flies with some backyard compost when I transplanted my peace lily, and I think they bred cuz they were all over my room! I felt bad and I opened my window, and I saw a few fly threw the screen, but they just don't have that much intelligence for all to escape. Anyways, I had a bucket of water out and I noticed that their were a bunch of dead fruit flies in there (they die instantly when they hit water) and I got thinking....maybe my betta would like one because they ARE insectivores. So I fished out a few and he gobbled them up. Then I gave the rest to my tetras and they loved them too! The tetras must have been really sick of their generic tropical flakes cuz they jumped out of the water. Its kinda funny seeing 1" fish leap out of the water like pirrahnas and splash water on the side of the tank.
