I have a 60 gallon saltwater tank with 80 pounds of live sand and 92 lbs of live rock. I am using two 1050 gph koralia powerheads(new design) and I also have a rena canister filter and a rena smart filter with the 300 watt rena submersible heater. It has been up and running for 3 weeks now and I just added two clown fish last night and they went straight to the bottom corner of the tank and they are staying there. The bigger one ate a little bit last night but nothing today and the other one is not eating nothing. It has been only one day. They both seem to be breathing hard and the smaller one stays in the same area and sometimes goes on his side. I have checked everything yesterday and today and it is reading where it needs to be. I have two cleaner shrimp, 4 mexican turbo snails, 5 hermit crabs and a lawnmower blennie. They all are doing great. When I turn the lights off the two clown fish seem to move alot more. I would appreciate any advice
