Hello everybody,

I saw this zebra hiding in cave and then i see the red spot on the head so i take picture and start change the water and clean the aquarium. I let the zebra stay isolated in the tank. he seems to be eating.

Can this be lesions?
bacterial infection on the skin?
can it heal automaticly after a while with good water condition?
Do i need to use medical in that case what type and advice?
do i need to isolate the fish in seperate tank or can the deases spread to other zebras?

Please help, i have attach pictures

thank you

Most definitely get some Kanaplex or something to treat a bacterial infection. It can't hurt.
