I have two small clowns that are acting different. First they are breathing fast and they look like they are being lazy on the bottom of the tank. When I say they are being lazy I mean they look like they are resting on the bottom "swim a little them it looks like they sit a little". I have checked nitrate,nitrite,ph,ammonia,alk,temp is 79,salinity is 29, everything is where it needs to be. This pair has been in the tank for about a week and a half. They are the only fish in the tank. Tank is a 10 gallon with an eclipse hood system. There is about 6 lbs of live rock and a 3" bed of crushed coral. PLEASE HELP
