Until last week I had 4 silver sharks in my tank - then last Wednesday one popped its cloggs which I wasn't too worried about it happens from time to time. Then over the weekend I noticed that one of the other's dorsal fin and little fins on its tummy (sorry not sure what they are called) had gone red and it didn't look very well - just floating around a bit and not rushing around as normal. I inspected the tank this morning to find it belly up. I've tested the water and all seems ok. Have they got something that I need to be medicating? All the other fish seem fine.

Any help greatfully received

Have you checked this post? .. some good links and maybe you can identify what the problem is with them.. it might be skin flukes, septicemia or costia.. or none of the above.. compare symptoms to what you see there. Are the other silver sharks looking normal & acting normal?

the other sharks and other fish in the tank seem fine too. I can't seem to find anything like what the 1 with red fins had on the list of diseases. Guess ill never know what the matter was

There are a lot of these 'mystery deaths' with fish.. I guess vet. science still have a lot to learn about them. Since all the others seem fine, I wouldn't add any meds. Good luck with your tank.

Welcome to fishlore Katfish, sorry for your loss! :'( Any time you have a problem with your tank like that the first thing I would recommend, even if you don't know what caused it, would be a 50% water change. It can help, especially if the water parameters are off.

Is this a new tank? Have you been testing for ammonia, nitrites, and nitrates? If so what are the readings? If you test these and let us know, we may be able to give more suggestions. Best of Luck
