I currently have a sarasa comet goldfish and a moor goldfish. I got them from a small local petshop (which is closed down now and was open less than a year). I got the sarasa first. I got these fish completely on the suggestion of the owner of the shop. I have a 23 gallon tank. After looking through google and these forums I found that the sarasa is meant as a pond fish, not an aquarium fish! I am so sad. He is our little buddy. We are working on a 75 gallon tank and were moving both gomdfish to it when it is ready. Can we keep him in there?
