i took it out, i just checked out the tank this mourning and I only saw one fish that looked like he might be sick. He is kinda floating around with the current of the tank. Im guessing something must have got into the tank water but i got it out before alot of them got harmed from it. I cant see any other reason. Im guessing I might lose one or two of them but it doesnt look to bad right now. Its just really frustrating to put soo much care into these fish and see some of them get sick. I feed them only the best, and do excessive water changes just to make sure they are in the best conditions possible, and somehow some of them get sick.
