This has been a fish in tank cycle with 2 clownfish. 3 weeks and 2 days up and running. Ammonia and Nitrites have been very little to non-existent along the way until now. I have been testing twice a week. I tested for Ammonia 4 ppm and Nitrites 1-2 ppm and little to no nitrates as of 2 days ago. Today I completed a 50% water change and appropriately dosed bio-spira to the tank. Today is the first day I have noticed odd behavior and discoloration in 1 of the clownfish pictured above. The other is perfectly fine and seems to be doing well.
The best I can say to you cause I’m also fairly new is to get the fish out give to someone to hold on or back to lfs let your tank cycle because fish are getting hurt
Cycling a tank with fish is very common.
Old school, there’s is better ways to do it nowadays one being patience’s
And now you see why there are new improved methods which don't require harming fish.
My other fish is 100% healthy and active
He was swimming in an uncycled tank with a high ammonia level. Perhaps he is stronger then the sick fish. Get back to us in a few days with an update. Sometimes the internal injuries caused by ammonia poisoning take a little time to show. Please don't add any more fish until your tank is cycling properly. Check your filtration and media. Add nitrifying bacteria and make sure they have something to colonize on or in.
Filtration and Media checked. 50% water change and bio-spira added today. Will give an update.
I hope your fish survive. Make sure you have good surface ripple for 02 gas exchange too.

What size is the tank?
