(Initial onset late December)

(Last week)

(Today)

I have had an interesting case with one of my silver dollars, approximately nine years old. A little after Christmas I noticed one of them had a lump on its side. This lump has been changing in shape and size the last month and a half. Today it almost has a little dimple in it. I was thinking it had a tumor and I expected it to get larger and larger until it eventually killed the fish. But as I said, the lump continues to change it shape and size. Has anyone ever seen this before? This fish does hide behind the plants all day, unfortunately, but always comes out to eat. It is not pecked at or harassed. I don’t know what to make of it. Has anyone ever experienced a case like this, even on a different species of fish?

The photo collage is numbered. So the first notice of the lump is picture one and so forth. This is over a span of a month and a half I would say.

My guess is that at nine years old the aging SD's immune system is weakening and that the growth is an iridovirus tumor, (Lymphocystis).
Those type of growths can increase in size if the fish's immune system weakens, or shrink, even disappear if the immune system strengthens. It's not very contagious, not usually lethal, just ugly.

Besides stellar water quality what other way can I boost the immune system? Thank you.

I feed romaine lettuce and zucchinI in addition to frozen, dry flakes and granules. I sometimes use garlic juice too.

You've obviously done a great job keeping your SD's. Keeping any aquarium fish alive for 9 yrs. Is quite an achievement.
Your feeding regime is far above & beyond that of most fish
keepers. As you know even the most experienced keepers occasionally run into problems despite our best efforts.
Oddly enough, after three decades of fish keeping, I recently had to deal with my first case of Lymphocystis on one of my Mbuna. Two tumors emerged on one side of the fish. It took several months, but the tumors eventually became large enough to impair the Mbuna's swimming ability. He became a target for the other cichlids so I had to euthanize.
IMO, CB's suggestion of vitamins seems to be about the only way of improving your already top notch feeding program.
If things improve let us all know.

A201. Thank you for the compliment!! I am sorry to hear about your fish loss. I am afraid that is going to be the fate with my Silver dollar too, eventually. I will definitely look into the vitamins—even temporarily I guess. I feel the prepared foods like the flake and granule should have enough vitamins and I’m afraid to overdo it. Thank you again.

The plot thickens! This is looking like a big pimple. I wish I were brave enough to net the fish and gently put pressure to see if I could extract whatever it is.

I feel like I am dealing with a big pimple on my silver dollar. For those who haven’t seen my thread which is fairly recent, I have posted videos of what the lump originally looked like and over the course of a month and a half the lump has change size and shape. This is what it’s been doing over the last two days. Has anyone ever seen this? I don’t think I have a terminal case anymore. Just see for yourself.

Original lump late December:


2/11/19. Changing shape and showing dimples:


2/13/19. Opening up


2/15/19. Totally opened up. Whatever it is. Tissue? Benign mass? just fall off like a scab? Will the skin heal itself? Going to do another w/c right now.


I will add to this post over the next few days for anyone interested in seeing the progression. Please watch post for updates.

No one looks at old threads. That’s why I started a new one.

Whatever the original cause of the lump, at this point I'd consider treating with erythromycin just to prevent infection.

Boy do I have a story! I looked up aquatic specialists in my area and there is a man who works out of a local emergency vet clinic. But I know it would be a least $100 plus just to walk in the door and I’d have to net the fish and take it there. I found him on Facebook and sent a message and asked for help. He had an office staff get back to me and he called me himself. He says it could very well be an abscess caused by an infection and the cells attacked it and now that it took care of it the body was ready to get rid of it, thus the abscess. Of course it would need to be seen under a microscope. If it has bacteria it’s an abscess but if it only shows abnormal cells then it’s a cancer. He’s going to be away for 10 days. He says if the wound looks worse then to use an over-the-counter medication for gram negative bacteria. For now, he says to watch it and do nothing. The salt was good. He also said fish are resilient and it can very well heal itself. WOW!!
