Hello i have a couple questions about my 55 gallon saltwater tank. I have a eheim pro 3 canister filter on my tank with a couple powerheads for water movement. i have 30 pounds on live rock. 25 hermit crabs, 4 fire shrimp, 1 clown goby, one shrimpgoby, and one Back flip butterfly. i have had my tank running for about 7 months. my water readings are ph 8.1, nitrite 0, ammonia 0, calcium 380, Kh 13 dkh, nitrate around 10 ppms. i just bought the backflip butterfly a week ago and he seems to be a bit stressed. i did a water change and during the water change he was zooming around the tank and looked happy. but now he is just kind of hiding and his gills are moving quickly. i am going to buy a protein skimmer with in a week. i was wondering if it was a lack of oxygen in my tank or something like that because i have notice some of my other fish gills moving fast at times.
