Sick Pearl Danio

[ivanfral]

Hello,

Since I dont have a quarantine tank I bought and introduced two juvenile pearl danios to an aquarium with already four of them. Both of them got sick pretty soon turning pale, swollen, lost appetite and with fast breathing and spasms. They died and the other three adult males did too after a while. Now this female has been having the same symptoms for a couple days. Notice the weird scale shape on the video.

Any idea what can it be? I started treatment with esha 2000 but it didnt work on the last one.

Not an expert but she looks like she's pine coning, it may be too late to save her and could be kinder to humanely euthanise but wait for other's feedback first! No idea on the cause but sounds like the new fish have potentially introduced something pretty devastating into your tank. Sorry you are going through this!

bad case of dropsy, euthanise it because there's no cure.
