Looks like a buoyancy problem to me - the way the fish is angled, all that work just to stay in one place. I'm not expert on sick fish, but that's where I'd start: on anything that impacts their swim bladder.

See thats what i thought, cuz i found the one that died yesterday belly up.
How ever theres no swelling at all.

Yep, nothing externally visible that I can see, but it's clearly struggling. Every time it pauses to rest, it sinks.

I've been thinking about this, and if it were my fish, I'd probably try moving it to a shallow container, like a dish pan or something like that, with a few soft plants for cover. See if the fish can rest when it's not surrounded by other fish and doesn't need to fight to stay high in the water column. Then I'd do a big water change on the main tank and watch for more victims.

Sorry Sucks when they get sick for no obvious reason.

Update....ive noticed their top fins are clamped and they have a cloudy look with veins on the abdomen.

I hope this is clear enough.
Its odd because ive had this issue before.

Not healthy looking fish. Are you using test strips or liquid test kit?

 

[aseradyn]

"Cloudy", like a fungus maybe? Spitballing, here, 'cause I'm way out of my depth.

You have had the issue before? Did you ever solve it?

Other than going back to basics (water quality, stress reduction, and nutrition), I'm not sure what to try, without an unambiguous symptom.

But that photo does look like unhappy fish

Yah i use a full test kit + kh/gh and tds (180 btw)

Temp is spot on 77degrees
Ph always 7.5
Ammonia 0
Nitrites 0
Nitrates 20ppm
(Peramiters all normal before waterchange)

I had this happen once before and the fish died but the others survived.
I noticed this and i thought about last time (the veiny belly and cloudy marks)

Costia?
Last time i treated with an ich med. and temp to 80
So ive used the same again, we will see...

 

[bullyboy]

Its interesting because it only ever effects the Rasbora

 

[bullyboy]

Ive also installed a really good UV sterilizer so i hope that helps as well.
