I brought home 2 false perculas' about 2 days ago. They are my first fish since I cycled my tank. Everything checks out (salinity, ph, no ammonia, no nitrite, nitrate~20, temp, etc). The fish looks overall healthy, don't think it's ich or anything. I'm reading and finding out my oxygen level might be low.? I'm not sure my skimmer was running properly. The other clownfish appears to be doing fine. I noticed a spot of sorts on the clown that is laying on the bottom and breathing very rapidly. Almost looks like he is injured. The spot (or cut) is just on the middle white stripe on his body, you can see it in the picture. Ever since I got him he has been swimming very erratic and almost looks like he is having seizures sometimes, with short quick movements so fast that it looks like he just appears in places without even swimming there?
Please take a look at this picture and let me know if you have any advice. Thanks in advance.
