For at least a week now my two Dwarf Gouramis (1m/1f) are showing some alarming signs, eating and moving less, losing some scales, one of them has damage to his eye that's not healing. I have purchased them a month ago. They're sharing a tank with 4 Corydoras (bought from the same shop) and 3 snails. Is there any way I could help them? Is it possible that it's Iridovirus and I won't be able to do anything to help them heal?
If its the Iridovirus, what do I do about the tank inhabitants and environment/ decor (live plants, rocks, substrate/ gravel)?
The water parameters are as follows: pH is 7.4, ammonia, nitrites and nitrates are all 0. Lights are on from 4 to 9pm on a timer. Fish were fed once every two days like suggested by our fish shop until the cycle is stable, Stability was added daily, Prime every other day.
