Hey guys, I just got 4 new fish. Two 2 inch koi. One is gold and one is silver. The other fish are shubunkins. One of the shubunkins is a sky blue one. They ate right away after I put them in the tank. Just so you know, I don't intend for these fish to live in a small aquarium forever. Once they get larger, I will put them in a kiddy pool with a filter and heater in my basement. So the problem is they look really scared and I feel bad. They are all huddled up in a little group and freak out whenever I feed them or turn the lights on in my room. Does anyone have suggestions to help these little guys settle into their aquarium?
