im puzzled as to what the fuzzy spots could be... i hope they pull through, sounds like youre making a heck of an effort. no casualties yet right?
Mike, as per my reading I found it to be marine velvet. Marine velvet are of two types , one that spreads and one that stays confined to a small region on the fish. This one stayed confined to a region.
Also there was secondary infection of fin rot.
Currently the fin is growing back up. The fish is eating well. There was a spot where the fish lost scales and now its recovering.
I cannot take the full credit, I did the reading part of it and my wife is doing the execution part. But yes I did not want to loose the fish and also I wanted to learn how to deal with situations like these.
The dark patch on the fish is about 85-95% gone. The fish is chasing food and eating well. He is still in QT and I plan to keep him there for the next 4-6 weeks.
The fin rot is no longer there, the dorsal fin is regrowing and I am hoping in a 4-6 week time period it should be ready to be put back into the frag tank.
So to summarize the treatment:
Set up QT
- 15g QT has hob filter
- power head
- few pvc pipe pieces
Sponge from display was put into hob filter to do bacteria seeding
Fish was fresh water dipped for 3 minutes and put in QT
The water was treated with copper ( dose was as shown on the cupramine bottle)
Weekly water changes to keep up with ammonia build up.
