Hello! Friendly beginner here, so my clown has the blues, well, more like the whites, I’ll start from the beginning, I got a Chromis to cycle my tank(stupid, yes ik) about 3 or 4 weeks ago, he was exposed to about 1ppm of ammonia, however I did use bottle bacteria so it didn’t get too bad, I noticed 0 ammonia burns on him, After the ammonia levels went to 0, I added a firefish and my clownfish into the tank(20 gal btw) was it stupid to stock two fish at a time, yes, but I’m known for being impatient. After that The Chromis seemed fine and healthy, however I believe he was struck with uronema, he got two big old white sores on him that eventually turned into Red sores and I lost him, now my firefish and clown has ich and I am treating it right now and I’m mostly concerned with why his fins are like falling apart, the firefish is the same, is it possible that there’s fin rot and ich or like what
