[SLuRpIe!]

hm, one of my bettas has a white head... what does that mean? and also how should i treat my betta [ slurpie ] 's tail cuz due to previous tail rot >=[ when i didnt know anything about bettas it attacked

What's going on with Slurpie now? What kind of white head? White scales or fuzzy,cottony stuff?

Extra water changes will speed up regrowth of his finnage

slurpie's doing fine besides his fins =/

er the other betta has white scales on the face and around the place where he flares its red with 2 stripes on each side

is it anything serious ?
