Need help with figuring out what is wrong with my apistogramma agassizii.

[Dave321]

Over the last day and a half, i’ve noticed this bump on my apistogrammas stomach. I’ve had him for about 5 months now.
Water params are: ph: 7.8, ammonia 0, nitrite 0, nitrate 5.0ppm. If anyone could help me out

it would be great!

This template contains the most important questions to be answered when dealing with sick or dead fish to find causes and advise on treatments. Please copy and paste into a new thread and answer the questions as precise as possible. Water parameters should be given in numbers. "Fine" or "good"...

Please COPY and fill out the template. It takes a more thorough anamnesis.

And add a picture of the whole tank, please.

In my opinion, the following conditions could be responsible.
A) Infection with Myxobolus spp.
B) Ulceration caused by Aeromonas bacteria
C) Lymphocystis, caused by a virus

A) Infection with Myxobolus spp.

Occurs almost never in cichlids.

B) Ulceration caused by Aeromonas bacteria

From all your options the most likely in my opinion.

C) Lymphocystis, caused by a virus

The thing looks stil subcutaneous, meaning Lympho is out.

I would say it's a cyst of some kind, but I wouldn't try to find the cause.

In any case it's unlikely that treatment will do anything.

Myxobolus certainly does affect cichlids—no question about it. There are reliable reports to that effect. As far as Myxobolus is concerned causing cysts in various tissues such as the skin, fins, gills, and sometimes the ovaries. These myxozoan parasites are found in juvenile and adult cichlids.

At this stage, there’s still something that can be done, but I agree with you that it’s doubtful whether the Apistogramma will pull through. I would use an antibiotic that’s effective against both Gram-negative and Gram-positive bacteria.

Not saying it doesn't affect them, but rarely found in cichlids. It's like we can get Anthrax, but it's rarely found in humans. You get my drift?

You ought to recommend a certain antibiotic then, but you know my view on antibiotics. Often too much too late and resulting in many side-effect related deaths.

Rarely? No. Its depending upon what kind of food (living) was given.
And about my thoughts about antibiotics, to fight Aeromonas, the fish is not dying of antibiotics, exitus will appear due to the infection.

How many cases of it have you seen in cichlids lately? I saw very few.

I wasn't talking about using antibiotics in cases or Aeromonas but in general.

 

[Eddy. E.]

C'mon Mac...lately...
Just germany or worldwide?

 

[MacZ]

No proven cases in Germany and no proven cases here on this Forum. At least from what I can gather.

Can you recommend me one?

 

[Eddy. E.]

Borgal 24% Solution for Injection:
24–48 mg of the sulfadoxine-trimethoprim combination per liter of water, corresponding to 0.1–0.2 ml of Borgal 24% Solution per liter of water.
Bath duration: 1–2 hours.
In the aquarium (continuous bath):
48 mg sulfadoxine-trimethoprim combination per 10 L of water, corresponding to 0.2 mL Borgal 24% solution per 10 L of water.
Bath duration: 24 hours. Higher dosages may cause damage to plants.
Repeat treatment: depending on the course of the disease, at intervals of 2 to 3 days until clear improvement is observed.

I'm no expert, but it looks like fungus infection to me.

Fungus does not produce cysts. It infects open wounds and causes symptoms resembling cotton wool.
