Hi everyone,

One of my female Gymnogeophagus 'Rio Yerbalito' has a growth in her gills causing her to have flaring gills, rub her gills on substrate, and extend her mouth. She's been rubbing herself on sand and decor for a while but that was the only symptom I noticed.

I looked into gill flukes but symptoms aren't quite the same.

The growth I'm referring to is the pink mass in the top part of her right gill.

Has anyone seen / experienced this before?

Thanks

The picture is cloudy, so I cant see any detail of "growth" in gill. I can see swelling and redness and gaping of gills by fish in attempt to take up oxygen. The mouth also appears to show oxygen stress.

Can you take a clearer picture of "growth in gills" you are speaking about? Is this only one side or both?

Additionally, need more info:
How long tank set up? Is it cycled?
What are the water parameters: ammonia nitrite nitrate?
Tank size? Other inhabitants?
How long have you had this fish?
Are their any other fish in tank exhibiting these symptoms?

Gymnogeophagus have very specific needs for substrate -- soft sand is required-. They are eartheaters and continuously sift sand through their gills. Have you noticed any larger pebbles from the substrate lodged in gills?

This species also requires 2-3 months of winter temperatures @ or around 60 degrees. Then, after this winter break, they can be brought into a heated aquarium. This is a necessity to keep these fish healthy. If this winter break isn't provided they are prone to bacterial infections.

Hi Discusluv, you've helped me before so thanks again for your reply.

Here's some more info with a better pic at the bottom:

Tank is a 55g south american community tank with angels, a pair of apistos, corys, and the gymnos. It's one year old and well cycled. My angels and apistos frequently breed. Lots of plants as well. Never any ammonia or nitrite and I maintain large bi-monthly water changes. Water changes are always done with cold RO. I know the gymnos need a cool-down and I've heard stories of success of them doing well without the cool-down. I'm mainly referring to stories of them surviving for long periods of time in Florida ponds. I know no cool-down period is far from perfect but I try to replicate it as best I can with the cold water changes. And yes, while there isn't sand in the pic, I do have sand in the tank. I just have it split where the right is more gravel and the left more sand.

Here's the catch -- I setup another tank and kind of put this one on the back-burner for a month or two. Nitrates rose way higher than I thought and I was looking at 100PPM. While I had fry survive the nitrates and most other fish were fine, I had two fish develop issues. One was an angel who developed a cloudy eye. It has started to heal since I flushed the system with two large water changes.

The other was this female gymno which has developed this parasite I haven't seen before. She's eating fine, and her scales, slime-coat, and fins seem healthy. No signs of ich like symptoms which made me think it wasn't flukes. She's the only fish displaying this in the tank. BTW, in the picture, the growth I'm referring to is the pink growth in top part of her right gill. She only has one -- her left gill is growth-free. Also, I've had the gymnos for about 9 months. I bought a group of six and have only lost one after he got a sudden swimming bladder issue and died -- I suspected it was from an injury with another male but it was definitely suspicious.

Thanks again Discusluv, hopes this helps with the diagnosis.

If it was gill flukes, you would see more of the fish rubbing their gills against objects in aquarium.

Being that the fish looks otherwise healthy, is eating and acting otherwise normal, you can eliminate ( for the most part) this being bacterial.

Given the clearer picture-- it doesn't look as red around the gill area. Actually, it looks like a tumor or lymphocystis. Obviously, there is no cure for a tumor and lymphocystis, being viral, has no "cure". However, the later can be controlled with good water quality, nutrition, low stress. Being that you had an issue recently with water quality, if this showed up afterwords, it will point more to lympho.

UPDATE 2:
About 2 hours after posting this the fish was dead. She was buried in my yard. RIP . Anyways, I examined the mass. It immediately gave way to blood and puss when I poked it with a toothpick. Also, please see her very inflammed egg tube and anus (if thats what you call it). I would really like to know what this was... anyways here are some good pics

UPDATE 1:

Hi Discusluv and others -- I wanted to provide an update on the fish's health. I will include pictures at the end. I am worried for my other gymnos now and am looking for a proactive approach to fix this issue. I have been trying to minimize stress by keeping water clean with large weekly water changes.

To summarize, this disease has had a lifecycle of its own and my fish isn't doing too great. The mass in her gill continued to grow. It started out as pink and relatively intact and smooth -- very fleshy. Once it grew it turned white, stringy, and mucousy. When it was at its biggest point, she was struggling to breathe, often spending time gasping at the surface.

The mass then started to get smaller and for some time, I had hoped she would make it through this. While the mass is still there, it is much less noticeable. Unfortunately, the disease has progressed to different symptoms. Her scales are starting to protrude (not as pronounced as Dropsy but still there), her fins are starting to fray, and she has a white spot on her back which I believe is some kind of sore. She is acting very lethargic and I don't think she has much time left.

Also, after doing a water change the other day, I noticed my other gymnogeophagus were rubbing themselves on the substrate and decor, which was the first symptom I noticed on my very sick female. While this behavior has subsided, I am still stressed out as I am proud of growing these fish and am attached to them. Are there any preliminary measures I can take such as aquarium salt in the case that the rest of the gymnos are sick with this unknown disease?
