What does this look like to you guys. I don't see this on any other fish.


Tank history:

This 60g tank has always been healthy, recently i transferred all my fish to my 300g. Well I started the most awesome job in the world recently and I travel quite a bit. Well I been focusing so much on my 300g at some point I missed a water change and all my levels were way off. This killed off a lot of my cichlids in my 60g including my beautiful electric blue/powder blue jack dempsy :(

During that time I had my fahaka puffer in the tank with those guys and I was thinking he was offing my fish. Turns out he was not, but I placed the sharks in my sump, while I made some changes to things. My filtration system was messy and it's possible the fish ate some filter floss cause it was everywhere. I have since made an awesome cartridge for the sump tank which has resolved that issue.

The disease:


So both of these sharks I got from the same mom and pops aquarium place, they were from separate tanks.

The really bad shark i noticed had a very swollen belly at one point. Then weeks later I could see blood in its belly. Now the fish looks like it's a skeleton, but I finally seen it eat today and I do not see blood in it's belly anymore. The outside of the fish looks like it's skin is peeling off almost. It's white like Ich but it does not appear to be ich. There are almost strange skin growths on it.

The other shark I see this on only one fin on it's right arm, other than that he looks very healthy and full.

I picked up a 3rd shark today and I do not want it to catch this disease, because he's good size and I really want a shark in my 300 gallon. I'd rather get rid of them if it's not something I can resolve or if it's going to kill my other fish. I can't baby sit my fish as much as I wish I could anymore.
 
Your post is a bit confusing. Are the sharks in the sump, sixty, or three hundred
What is the temperature and water parameters

Sharks were in 300g sump tank with filter floss for 2 weeks. The sharks have been moved up stairs in 60g tank for a little over two weeks now where they are currently.

Water parameters were bad with low ph in 60g tank. Yesterday I changed water and cleaned filter.

Before water change in 60g
PH was below 6
Nitrogen was .25
I forget Amonia

After water change:

PH is 6.6
Amonia 0
Water temp 76
Nitrogen is now 0 I believe.


I will do another water change tonight to get it into the 7s

Does the shark at the top of the tank in the video have ich? It appears to have something on its fins but I can't make out what.
 
Tough to say - you might be seeing more than one infection (primary and secondary). The bloated belly with blood in it makes me think mycobacteria, which is very nasty. It often affects the kidneys and results in dropsy. Strong, gram-negative antibiotics could fix it but often times it never goes away forever. Mycobacteria form granulomas that make them resistant to treatment. Sometimes (especially with goldfish) the typical method is to euthanize. I'd try some kanamycin or something first though.
 
The other fish lived but that one died. I think it had a problem from the store. My other guys are very healthy now and growing fast :)
