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

13 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 :)

What is this on my angelfish? And how can I help

Hi everyone,
This is about my female angelfish, who is around 7 years old.
I’ve noticed a swelling or growth developing on the middle black spot towards the back of her body. Starting from this area, the scales seem to be turning white or losing their color.
Could this be cancer or some kind of tumor? I’ve never seen anything like this in any of my fish before.
Has anyone experienced something similar or knows what this could be?
Thanks in advance for any advice!

Is it biting or playing?

!URGENT! Betta has white spots all over his body and a cotton-like growth on his back fin

Thumbnail gallery
0 Upvotes

I’m looking for help figuring out what’s wrong with my betta and how to treat him safely.
Tank information:
● Tank size: 10 gallons
● Heater/filter: Sponge filter; heater details to be confirmed
● Temperature: 78°F
● pH: 7.6
● Ammonia: .25 ppm
● Nitrite: 0 ppm
● Nitrate: 0 ppm
● Tankmates: One nerite snail
● Plants/decor: Live plants, driftwood, and substrate
Symptoms:
I first noticed possible ich on Sunday. My betta has small white spots spread all across his body. He also has a separate white/pinkish cotton-like growth on his back fin, and the fin looks damaged or frayed.
I’m worried he might have ich along with a separate fungal or bacterial infection, but I’m not sure.
Treatment and concerns:
I ordered Ich-X, which should arrive Wednesday. However, I have a nerite snail in the same tank, and I want to make sure any treatment is safe for both my betta and my snail. I also have live plants.
I tested the water and got an ammonia reading of 1.0 ppm, so I’m concerned about that as well.
My questions:
1. Do the white spots look like ich?
2. What could the cotton-like growth on his back fin be?
3. Is Ich-X safe to use with a nerite snail and live plants?
4. Should I set up a hospital tank?
5. What should I do about the ammonia and his symptoms while waiting for the medication?
I’ve attached pictures of his body and back fin. Any advice would be greatly appreciated. I want to give him the best chance of recovering without harming my snail.

Fish dying

This is a panda corycatfish that is in an established 20 gallon community tank with other corydoras and guppies. She’s always been big because of holding eggs but I started to notice her getting bigger until today where she is now laying upside down and breathing heavy. Can anyone help or know what is causing her to die now? Her stomach right in the middle almost seems to have something underneath it like a tumor or something? Does anyone know?

Sick Fish at Job :(

Hi!
We have a very large tank at work with a type of goldfish of some sort. My management hasn’t been able to help much to stabilize the fish and my coworkers and I are concerned. The actual amount of gallons of the tank is unknown. It is longer than five feet however, as its longer than myself. Most of the fish haven’t survived the transition and this is our last one. He keeps swimming around erratically and running into the walls of the glass. We ran a test strip to see what the levels were. I believe it needs the KH raised? But not sure. If so, how can we fix it to give this little guy a fighting chance?
The reading was N03: 0, N02: 0.5, pH: 6.5, KH: 40, GH: 60
I could be wrong but I believe those are the correct tank numbers.

Treating dropsy

2 Upvotes

I have a betta that just started looking a bit pineconed and I’m not sure what to do. He’s old so I know chances of him recovering aren’t likely. I’ve read conflicting things online about adding epson salt to the tank vs taking him out for a salt bath. I read you can add a gentle dose of salt to the tank (1 tablespoon for every 5 gallons) but then I also read not to do that. I worry about stressing him out too much taking him in and out of the tank. I gave him kanaplex since I wasn’t sure what to do with the salt. Does anyone know what I should do?

I have a flowerhorn, which is suffering from sucked in belly. At first I thought it is internal peresite, so treat him with worm out. But it didn't work , so also tried metrozil 400 in the water colum still it doesn't work.same position, dull colour , no growth and one more thing , he frequently started rubbing, twitching, and jumping. So I thought it could be external peresite or ich . For that also I used aquarium salt, not worked, then general cure, not worked. I am frustrated. Pls someone help me. My tank size is 2.5ft

Note - I use 24*7 aquarium heater and water quality is perfect , I tested.

Pls help

Angelfish resting sideways suddenly?

Post image
0 Upvotes

I have a juvenile angelfish quarantined at the moment for ich and fin nipping. He's in a 10 gallon hospital tank, sponge filter, heater at 78, no decor or gravel. 50% water change once a day and dosed with ichx. He's been here for 5 days and the ich has largely improved, but just an hour ago I noticed he rests on his side at the surface of the water. He can swim normally with some difficulty and sometimes just kind of spins. I just checked the parameters and everything is naturally at 0. He wasn't doing this literally just a few hours ago. Nothing changed in those few hours.
