So I just bought 2 new clownfish for my salt water tank a couple hours ago, and ever since they were in the bag they were breathing super hard. This is my first salt water tank so I’m super inexperienced in this, but I have been keeping freshwater successfully for a couple years now. So 5 hours later, one of the clownfish is acting completely normal, and the other is still breathing heavily. I read that I should do a water change due to a potential ammonia spike so I did a 40% water change and an hour later that one clown is still having trouble breathing. Also to note, the clown having difficulty breathing has a weird dip in his stomach , in fresh water usually means a internal disease of some sort. I just tried feeding them and both ate a good amount, which I assume is a good thing. I don’t know if I’m overreacting and should give it more time, or try to fix the problem now. Any suggestions would be great!
