Tb?

[thechosen1]

Hello all! I recently came back from school to discover one of my Leopard Danios had a misshapen spine and had lost quite a bit of weight (it had previously been rather fat and healthy, and is the oldest member of the tank, being 4 years old).

Here are the stats:

Tank size: 10 Gallons
pH: 7.3
tank temp: Between 79-83F

Fish Symptoms: The Leopard Danio's back has suddenly become misshapen. It continues to eat and play with it's companion.

Volume and Frequency of water changes: I usually change 1/4 of the water every 1-2 weeks, and do 1/2 water changes every 2 months.

Chemical Additives or Media in your tank: None

Tank inhabitants: x2 Leopard Danios, x2 Pineapple Swordtails, x1 Cory, x2 Serpae Tetras

Recent additions to your tank (living or decoration): None

Exposure to chemicals: API Algeafix

Zebra danio's spines can bend it old age. It could just be old age.
Also bent spine and being skinny can also be internal parasites.
Signs of internal parasites are long stringy white poo, or clear mucas poo.
Worms prutruding from the anus.
Being bloated or skinny.
Enlarged anus or red inflamed anus.
Swimming on there sides sometimes.
Bent spine.

it's unlikely to be TB and is more likely age. Zebra Danios don't live very long and 4yrs is ancient for them.
With TB the fish usually puff up like a balloon, do a stringy white poo, and stop feeding. Then they die a short time after that.

First off, thank you for your responses. My father insists that I kill the fish as soon as possible, but I don't feel that this is necessary. No other fish in the tank are sick, and as far as I've observed, I have not seen stringy/clear excretement from said fish. We really don't have a hospital tank, per say (it was a pretzel bowl with a heater), and I'd like to avoid separating it unless it exhibits more frightening behavior.

Thoughts? Comments? Thanks in advance.

as long as the fish is still feeding and swimming around normally, then leave it be.

If it stops feeding and hangs around the surface by itself, does a stringy white poo, or lies on the bottom breathing heavily, then knock it off.
