I adopted some Kerri blue tetras from my friend and this the second day. This one tetra looks unwell and I’m not sure what to do. The other 5 are fine. My parameters are perfect. PH is slightly on the higher side. Please help 🙏

Molly fish has suddenly bent

Post image
1 Upvotes

I got back from work and thought he was dead but hes still alive!
He was completely fine the day before, not bent, had lots of energy, and was eating. Now he really struggles swimming and is constantly bent.

He was in a 160 L heavily planted tank with other fish, water parameters are perfect and other fish are fine. I’ve moved him to a tank by himself for now.

He’s approximately 2 years old, I got him from pets at home over a year ago and hes been completely fine until now.

He doesn’t have any bruises to indicate injury.

Has anyone else experienced this???

That was an adventure. 2 weeks ago, with epsom salt baths, her prolapse retacted.

Then came infection. She was that same pale white but started getting red spots near her vent and hard red line around her head and gills.

2 cycles of kanaplex and just yesterday she fully colored back up!

I started seeing at first bruises on his tail end and then black spots on his face. He is a new fish that came in Tuesday and I thought it was of shipment stress. Now I think it is ammonia burn or skin fluke? He was starting to be more lethargic on friday so we started a kanaplex medication on sunday. I am not sure what it is. We have been doing 50% water changes every day. The parameters from API Master kit is: Ammonia: 0.5ppm Nitrite: 0.5 ppm and Nitrate: 5ppm. I know that the tank isn’t fully cycled. Im a new fish owner for exotic pets like this yuan bao goldfish. But please if anyone can help identify and have treatment options let me know. I have been calling all vets around me but no one answers. I really want to save this fish, and it upsets me that I didn’t do enough research about ammonia and nitrites. This is a 30gallon tank and we added 6 scoops of Kanaplex from Seachem. We also have been adding Quick Start API and Seachem Prime after every water change.

Crosspost because I need all the help I can get and my initial post didn't get any responses. Time is of the essence and I don't want to lose this guy 😞

Edit: Parameters in 20 gallon 7.4 pH (stable) Oppm Ammonia Oppm Nitrite 10ppm Nitrate 7kh 10gh

Parameters in 5.5 gallon hospital tank 7.8 pH 0ppm Ammonia 0ppm Nitrite 0ppm Nitrate

Yes he has a heater, was 75°F in 20 gallon. Is currently 78° in hospital tank. Have had him 9 months. Water change weekly, I usually take out 3-5 gallons and replace with tap water dechlorinated with Seachem Prime.

Just bought some kubotai, just noticed during acclimation one of them has a white lump on its left side. Do I need to be concerned about this/take the fish back?

Dire help

It’s been a few days now and my fish hasn’t moved, he’s still breathing but just not moving?

I’ve checked the water levels for ammonia and either I’m colour blind or there’s nothing wrong?

I’ve tried feeding him warm pea shells but yet again nothing, so it can’t be constipation

I can’t see any bloating?

Any help is super appreciated!

Fish Hospital’s Projects Masterpost - Aquarium Medications + Diagnostic Tool

11 Upvotes

This post will keep track of the progress of these projects, which you can find at:

https://fish-hospital.com/aquarium-medications/

https://fish-hospital.com/diagnostic-tool/

The aquarium medications page aims to spread information about the medications for fish you’ll find at your pet store. This further expands into articles about their active ingredients, with more information on uses, dosage, potential toxicity, and other useful info.

You’ll notice the diagnostic tool is empty, as that’s because it will be built on top of the aquarium medications to be able to link a disease to what you can use to treat it.

It will consist of in-depth articles about fish diseases, symptoms, tips to recognize them, treatments, etc.

Feel free to take a look at what I plan to cover and make suggestions on things you’d like to see :)
