I have a pond that is around 2,000 gallons. It is new so I have not put any fish in it yet. I got my first fish tank and put 3 comet goldfish in it to get the cycle started. Then after that I put them in the pond. They were about 2, 2 1/2 inches long. I saw them the day I put them in and the very next day. But after that I have not seen them since. 2 weeks went on before I lost hope and figured something got them like a bird, but then my brother was working on the pond and he had to shut off everything and drain the water a little bit. He said when he was working on the pond he saw 2 of the goldfish. From the way he describes it, it sounds like they grew a couple more inches. To get to my question, why are my fish hiding and not wanting to come out? I go out everyday to look for them but I can not find them. We have a algae problem so it makes it hard to see them. Is there a way to make them come out? Are they afraid of ruff water because when the waterfall is going and the pump in the middle is going, the water is ruff. Any answers would be great!
