My boyfriend's fish Sashimi is in a 3 gallon unfiltered glass bowl with stones. We recently just got the fish a new silk plant and a little statue and did a full water change yesterday, but now the tank is weirdly cloudy. (like milky cloudy...white). We use tap water to fill the tanks, always have, and treat it with water conditioner. Why is his water all cloudy?! I've never had this happen before, and we did the exact same thing with all the other tanks on the same day, but only Sashimi's tank is cloudy... also, this happened 24 hours after the tank water was changed. It was perfectly clear before the fish was placed in the bowl.
