Hello! I have 2 betta fish, Rocky(veil tail) and Beau(halfmoon). They both got a brand new 5 gallon tank about 2 weeks ago. Each tank has a little decoration for them to hide in and a couple of plastic plants. I use tap water treated with Api betta water conditioner. Also both tanks have a heater, LED light, and a low-flow filter. Beau's tank is still has crystal clear water but Rocky's water is getting cloudy. What can I do to clear his water?
