Hello all. Looking for any and all theories on what is happening to our tank. We’ve had it for 3 years, during those 3 years we’ve had a naso tang, fox rabbit fish and 2 clowns that have stuck with us through random individual fish drop offs. 3 weeks ago we added 4 wrasses, one powder blue tang, 4 snails and 2 kenya tree corals. Adding the extra fish seemed like the best decision as the original 4 fish seemed much more active and didn’t hide in the rocks as much. Unfortunately, the fox face and the powder blue had a few scraps and one morning the powder blue sat at the bottom of the tank between the rocks and swam back and forth. He died 3 days later. While the powder blue was sitting in the middle of the tank, the naso tang and fox face started acting very strange. They would sit at a 45 degree angle and stopped swimming around normally. After the powder blue died, the naso tang returned to normal behavior but the fox face started acting extremely weird, sitting vertically tucked in the corner of the tank. We noticed some small white dots on him so assumed ich due to the stress. Thankfully, the remaining fish all had no spots and returned to their normal behavior. After the powder blue died our aquarium store came to check our tank and ran a bunch of tests and said everything looked fine but nitrates were slightly elevated. Our coral, snails, and new wrasses are thriving. We have been extra vigilant watching our fox face and he seems to be turning a corner swimming around the tank a bit again. This morning we woke up to a dead clown fish (wedged in the rocks bottom left) and the remaining clown has started swimming at the middle bottom of the tank which is out of character. Any idea what happened to our tank?! We are very sad to have lost our new powder blue but having a sick fox face and dead clown, who we’ve had for years, is heartbreaking. Any thoughts and insight is appreciated. Thank you!
