Harlequin Rasbora sick

[Mick85]

So i've noticed one of my harlequin rasboras mouth is constantly opening and closing and it hasn't been eating. It also seems to be less interactive with the other rasboras and tends to just hover in the tank on its own most of the time. None of the other fish in the tank have the same problem it's just the one fish. Anyone know what could be wrong with it?

pH: 7.4
Amm: 0
Nitrites: 0
Nitrates: 5.0
gH: 50-100ppm
kH: 50-100ppm

Any chance of a picture and short 60 second video of the fish?
If the pictures are too big for the website, set the camera's resolution to its lowest setting and take some more. The lower resolution will make the images smaller and they should fit on this website. Check the pictures on your pc and find a couple that are clear and show the problem, and post them here. Make sure you turn the camera's resolution back up after you have taken the pics otherwise all your pictures will be small.

If the video is too big for this website, post it on YouTube and copy & paste the link here. We can view it at YouTube. If you are using a mobile phone to take the video, have the phone horizontal so the video takes up the entire screen. If you have the phone vertical, you get video in the middle and black on either side.

---------------------
Do a 75% water change and gravel clean the substrate. Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

Add 2 heaped tablespoons of rock salt for every 20 litres of water. Keep the salt in there for 2 weeks and see how it goes.

Cross your fingers and hope for the best.

He means it's screwed....no chance of survival. Aussie slang lol

The fish has had it. When they breath like that and can't swim properly, they have internal problems and are struggling with the pain.

Any idea what could have caused it?

 

[Colin_T]

The most likely cause is an internal organ problem/ failure, possibly caused by bacteria damaging one of the organs.
