Sick fish?

[fishfood!!]

Can someone diagnose this fish? It has been floating in the same spot hiding between plants for a few days. Not coming out to eat during feeding times, like it used to. Today when I got home from work, it now has moved up to the surface and is just floating. I can’t see any signs. I am dosing API General Cure as I had fish previously die from what I believe is waste disease (sunken stomach).

Hopefully someone can see something that I am not seeing

The fish has red gills, inflamed gills, clamped fins and possibly a bloated belly. It also appears to have a opaque discolouration in the muscle tissue in the back, which could be microsporidian or just the light from the photo.

It could be gill fungus, bacterial gill infection or gill flukes.

It could have an internal bacterial infection like TB but that usually kills the fish within 24 hours of showing these symptoms.

--------------------------
I don't know what is in the API General Cure but you could try a broad spectrum medication.

To work out the volume of water in the tank:
measure length x width x height in cm.
divide by 1000.
= volume in litres.

When you measure the height, measure from the top of the substrate to the top of the water level.

There is a calculator/ converter in the "How To Tips" at the top of this page that will let you convert litres to gallons.

Remove carbon from the filter before treating or it will absorb the medication and stop it working.

Wipe the inside of the glass down, do a 75% water change and complete gravel clean. And clean the filter before treating.

Broad spectrum like API EM Erythromycin?

I just dosed the tank with api general cure (hence the white dots in the photo) but I will try the broad spectrum as you suggested.

Can you tell me what happened to these two fish? It’s a little graphic

Update to this fish

It’s now got a white stringy feces so I assume this is parasitic?

Do not use Erythromycin. It is a strong anti-biotic that only treats certain bacteria and will wipe out the filter bacteria.

Use a normal basic broad spectrum aquarium treatment, something that treats fungus, protozoan and bacteria, and that is not an anti-biotic like Erythromycin.

----------------------
The fish in the 2 pictures are pretty skinny. If they became skinny over a period of a few days to a week, it is either an internal protozoan infection or microsporidian.

Metronidazole can be used to treat internal protozoan infections but the only cure I know of for microsporidian is to add heaps of salt and make the water about 1/3 to 1/2 strength seawater and most fish don't tolerate that.

----------------------
Stringy white poop is common with internal protozoan infections and Tuberculosis (TB).

With TB the fish usually swell up suddenly (overnight), do stringy white poop, stop eating and hang out by the surface or near a filter outlet and breath heavily. They normally die within 24 hours of showing these symptoms. There is no cure for TB and it's not that common in danios.

Thanks, I think it should be protozoan than. The two dead fish were skinny for a while before I eventually found them gasping for their last breath on the substrate.

I have another emerald that is skinny but for some reason it has bounced back from being lethargic and not really eating ( now I see it at times chasing the bigger emeralds around). But it is just still very skinny.

It turns out Api general cure does contain metronidazole so hopefully after the dose period is complete, the issue will be solved.

Thank you [emoji51]

Do you have any other species in the tank? These are both incredibly timid species and can easily starve to death if outcompeted for food. They do best in large groups (15+). They are OK together as technically they are the same species even though one is called a danio and the other a rasbora .

The clamped fins do suggest an issue with either water quality or stress. My CPD do have some coloration around the gills but are also generally much brighter than the ones in your pic. Finally do you have plenty of plants to break line of sight? I have not seen this but have read that they can be aggressive toward each other, but this usually only results in torn fins.

I have 2 otos catfish in the tank but that’s about it. I know more is better but unfortunately I need to think about the water quality as I am REALLY pushing the livestock limit as it is. Yeah I know it’s two different species but they do shoal together. [emoji23]

As for the water quality, I would say the tank itself is doing excellent. The tank is heavily planted and the plants are thriving! I can’t even keep up with the trimming. Water parameters are 500-550 TDS 0 ammo 0 nitrite 5ppm nitrate 7.4 ph 4 kh 9 GH.

Here is a photo of the tank. Don’t mind the towel, i put it on top while dosing some meds so my cat don’t drink out of it and get itself sick. It’s a side view so not the best quality.

There is nothing in your water parameters, photo or tank mates that causes any concern.
I'm afraid that I have very little experience with illness or treatments (fingers crossed) so will leave that to those that do. I jumped into the thread because I keep CPD so know a little about them.

Before I sign out how long have you had your fish and when last did you add any. I do know that newly imported CPD have a fairly high mortality rate because they don't cope well with transportation or being starved during transportation. And the symptoms are quite similar to yours. I was fortunate to get a group of 25 from a shop that had them in stock for over a month before I bought them so thankfully managed to avoid that.
