Cardinal Tetras did I make a mistake?
So I bought 8 Cardinals for my 55 gallon I knew that they were kind of a finicky fish liking very low nitrates. But I didnt realize that they liked very acidic water below like a ph of 6. So I have had them for 3 days know and 2 of them are acting a little retarted I guess I would say. Swimming upside down banging agisnt things ect. I am assuming they are a bit stressed already. My question is, is it my ph being 7.2? Nitrates are 0 as of now same with Ammonia. water is 77.8 F. I called the pet store the ph of the tank the Cardinals are in is like 6.5 and they are tank bred not wild. He told be just to watch them..... Is there anything I can do to help them maybe some salt or copper?
