We cleaned our pond out a couple of weeks ago and placed a large batch of elodea densa that had gone on a massive growth spurt into another tank without fish. We noticed yesterday some baby fish about 1cm long swimming around. We’re not sure how many we have or what type they are. Can anyone provide any advice on this. We have put in an oxygen stone and have been adding some ground flakes for food. They seem to be eating from the plants. Any advice would be greatly appreciated. Photo attached of one we managed to catch. Thanks
