I believe my Black Molly has columnaris. He has what looks like a tiny cotton ball on his body just over his right fin. After researching that I needed antibiotics I decided to use Erythromycin because of what I read on the packaging while also adding salt. Next I find out that this was the wrong antibiotic and I only managed to kill my cycle but the white patch did go down. After removing the fish from this tank to another tank, I noticed that the white patch has come back after 2 days. First thing I did was add salt again and back to research. I found that Maracyn 2 is the preferred antibiotic so off to the store to pick this up along with new filters for my other tank with dead cycle. Come back home and check on the little guy to find that the white patch has gone back down.
So question is do I just leave the salt and continue to observe his behavior or just go ahead and medicate with the Maracyn 2, keeping in mind that he just came off of a whole treatment cycle of Erythromycin.
He is very active and responsive to me. When I come up the tank, he swims right up to me and swims back and forth begging for food.
I keep my tank at
On the new tank I dropped the temp by 3 clicks since this bacteria does not like cooler waters. My digital thermometer is spazzing out on me so I am unsure what temp is now. Plan on getting a new one after work today.
Any info is highly appreciated. Thanks.
