Fish Losing Scales

Recommended Posts

I've been keeping goldfish for the last 4 1/2 years and this is the first time I have seen this. One of my littler fish(around 3 inches long and an oranda) has lost about 5 scales on each side. He(she?) is acting perfectly fine. Just as chipper and happy as always. No gasping, flashing, or any type of odd behavior. No fin problems(red streaks, rot, clamping). No ich, no red spots, no hemorhaging. Just simply scale loss. Very strange. The other two fish do not have this problem. All are acting normally. The biggest fish has been in the tank for 3 years. The other two have been in the tank for a year. So no new fish. No medication have been given to this tank in over a year. I feed my fish Hikari Oranda small pellets, peas, bananas, oranges, green beans, broccoli, spinach, cauliflower, carrots, canteloupe, and occasionally fresh tuna and shrimp.

I haven't been to the board in about a year....but some might still know me.

Just to update, the problem is occurring in a 29 gallon tank.

There are 3 goldfish in it. Two are around 3 inches long and one is about 6 1/2 inches long.

This is an established tank that has been running for the entire time I have keeping fish(4 1/2 years). Nitrites are 0. Ammonia is 0. Ph is 7.2 Nitrates are within 40 range. Water change is due tomorrow. Tank temp is 72. Our city water is fairly hard.

I do a water change every Sunday. I remove 1/3 of the water. I use Aqua Safe.

No hollow ornaments in the tank.

There are 2 5/15 whisper filter pumps and 1 20/30 whisper filter pump lining the back of the tank. I have the extra filtration in case I need to set up a hospital tank...nice to have a cycled filter system.

Bottom has a thin 1/2 inch layer of gravel.

The tank is in my bedroom. I noticed the scale loss on one side of the fish 3 days ago. Now today there is scale loss on the opposite side too. I don't see how he could have injured himself. I suppose it's possible though. My fish are not breeding. I think I have tank full of males. I know for sure the biggest is a male. He bred with a big female several years ago.

Okay, my question is: Should I remove the fish with scale loss into a hospital tank and treat with a parasitic medication? Is it possible that feeding fresh shrimp and tuna could have introduced a parasite? Is there anything I could do to keep the fish in the big tank and help him? Would aquarium salt aid him in healing? Would aquarium salt potentially kill off a possible parasite? Thanks in advance.

Hi and welcome back.

Hmmm, if there isn't any symptoms of parasites I am wondering why you are going that route?

I would tend to sit and watch for long periods, see if there is any mating behavior or her/him hurting it's self on something.

There aren't any plecos in the tank are there?

Since the fish's life is not in danger at this time, I am going to move your thread to the regular diagnosis section.

The only things in the tank other than the 3 fish are two fake log tunnels. The tunnels are C-shaped so when they are in the tank, they have no bottom. Each end has a large opening and there is a large hole on the top. there are also fake plants attatched to the top.

Since the tank is in my bedroom, there are several hours every night that I get to watch the tank closely and I check on them off an on all day. I work at home so I know my fish's behaviors very well. I am at a loss. I don't get it. I will just keep watching them even more closely and see if I can figure out what's going on.

It probably is a double injury that happened a couple days apart. I read on the net that Myxosporidiosis will cause a goldfish to start losing scales. That's why I mentioned parasites. I know that fresh meat can introduce parasites. Probably isn't that, hopefully it isn't that.

I don't plan on doing anything unless the fish keeps losing scales/starts showing symptoms. I was just hoping someone was very familiar with why a fish would start losing scales on all different areas of it's body. Also if the exposed skin is at risk for infections/problems. And how long would healing time be...and if there is anything I could do help the process along.

I would keep the water top notch, this will help the fish to fight off anything going on. Maybe some salt, 0.1-0.3% would be good. And if the patches of missing scales look raw or infected I would put the fish on a medicated food. This will help to battle any bacterial infection starting.

:blink: Are you able to do a scrape on this fish? Often when keeping your tank in pristene conditions,fish can have parasites that are kept "under control"" Can you check the gills and see what color and how they look-are they red and meaty/pale,tattered? Also check gills for little white round nodules".
