I got in 6 green chromis and put them in a observation tank for 1 month, after 4 weeks I noticed that one of the green chromis had a red dot on its side. I got worried that these fish may have something wrong and went with a treatment for uronema I got off of Humble Fish. I ordered formalin and metro and started the tank on 1 scoop of metro per 10 gal every 2 days and started soaking all food in metro, I did this for 1 week before I had time to set up a new sterile system after the new system was set up I did the formalin bath for 1 hour at the concentration recommended from humble and transferred the fish into the new system. I then continued the metro at the same dose with the food soak as well. It has now been 2 weeks post the formalin bath and a total of 3-4 weeks on metro. The red dot has diminished in appearance, no other signs of infection have been noticed on any fish. I have had these green chromis for 2 months, except for the 1 red dot I have not noticed anything wrong with them, they seem healthy, eating well, swimming normal etc.
How risky would it be to add these fish to my display tank at this point? Is there anything I should be worried about appearing after 2 months?
Thank You
