So my girlfriend has this lovely all cherry red betta well recently he has been acting strange and today I noticed that his gills were inflamed, and he was breathing hard and fast.. she put stress coat and AQ salt into his cup which he has been qurantined in, not at the same time for the salt and stress coat. His breathing seems to have improved, but he is still breathing fast. now she is telling me that his face is turning a grayish white color and is starting to spread to his tummy. Is there anything i can do, or should we give up? thank you in advance for your advice :)
