Hey all,

I have a 20 gallon tank that initially had 3 danios to start. I lost one and moved the other 2 to a hospital tank so I can cycle my tank again. I’ve had some issues with my media. Anyways the 2 weren’t doing so good, so after some meds and time, one has come around a little but still not great. So I picked up 4 new ones and introduced them. One Danny is doing so much better now, but one remains at the bottom, seems to have a bit of a “hunch back”, does not seem to eat much and stays at bottom. Also Color is faded. What is happening???
ammonia is 0 as is nitrites and nitrates. ph is 7 and temp is 78.

If he has a hunch back that is not a good sign. It is always important to select the fish you want from the shop so that you get the best fish available.
 
pictures and video of the fish?
what is the ammonia, nitrite, nitrate and pH of the water?
 
A curved spine (hunchback) in fish can be caused by old age or a growth inside the fish putting pressure on the spine. There's no treatment for it.

Is the fish eating?
What does the fish's poop look like?

If the fish is not eating and does a stringy white poop, it is dying from an internal infection and should be euthanised.

It might be dying from old age, they only live about 3 years.

If you had an ammonia or nitrite problem in the tank, that could weaken it.

Generally when fish sink to the bottom and aren't swimming, they are on their way out. If it's not swimming, I would euthanise it.

I’ve had it only about 6 weeks 💔💔💔💔

What’s the best way to do that?

It swims sometimes, but not often 💔

Clove oil is the best way
