She got the tank April 15, new tank. There is 20 lbs of live rock in there, 32 gallon tank. She got her first 2 clownfish last Sunday. The water was tested by the store & she was told she was good. We were told not to change the water yet. Tested it today & ammonia was .5 ppm and nitrite .25 ppm. I’ve been dealing w/the same fish store. I called & they told me to put 3 capfuls of Stability each day and that maybe her filter isn’t strong enough. The fish haven’t really been eating and one just swims from one end to the other most of the time, my daughter read it could be stressed.
