HELP danio!!!

[Ami_bby]

I’m very much a newbie to fish keeping I have a 21 gal tank which I had 7 danios 3 white clouds 2 plecs and a few guppies. now I have only 3 danios I don’t know where the others went they just slowly disappeared the only theory I could come up with is them died over night and the others eating them. Anyways I see one of my 2 -3 yr old danios being lethargic and sitting at the bottom over a week. He doesn’t look well but just to let you know he’s always had a bent spine from when I got him it’s never affected him before.

he might have dropsy/pineconing

maybe he is also old, they only live up to 5 years

need pictures from the side that are in focus.

It seems like it may be something like dropsy or old age as Sgooosh said. My betta also dealt with this but sadly didn't make it. If you come to the conclusion based on his activity that he does have dropsy and notice that he is in his early dropsy stages, then start treatment with kanaplex, aquarium salt or methylene blue (there some articles online on how to do this). But it may just be because he's old.

It’s always best to start with aquarium salt, as medication should never be the first plan of action.
What are your water parameters? (Ammonia, nitrite, ect)
How long was your tank set up before you added fish? Did you cycle it?
How long have you had the fish? How long did you have them before they started disappearing?

hi, and to the forum, I'm sorry this brings you here.
we need more details about the tank and what looks to be a danio to assist you. We would also need some water parameters and clear pics.

Welcome to TFF.

7 danios 3 white clouds 2 plecs and a few guppies.

what sort of plecos are you keeping? bristlenose for example.
And the pictures make me wonder why the water is dark. do you have driftwood by chance?
And some water parameters could be a lifesaver at the moment. water parameters can be found using a simple test kit, if you dont have one already.

test kits are pretty inexpensive. here's 28 dollar one https://www.chewy.com/api-freshwater-aquarium-master-test/dp/121954
and for a last resort test strips are meh, and don't usually show ammonia

 

[Colin_T]

the red looks like a bacterial infection, assuming they have red on them and its not the picture.

what is the ammonia, nitrite, nitrate and pH of the tank water?

how long has the tank been set up for?

how long have the fish been dying for?

did you add anything in the 2 weeks before they started dying?
