I got a hurt bass that won't eat and gets bullied and is in a separate tank now. It's on antibiotics. It happened overnight.PLEASE HELPAs Grinch says, those pictures are not very clear however.. I also don't think its HITH.. Besides.. would he survive so long with HITH?
I have had in the past that red severums kept on coming up with something like you have there for no reason.
It never affected the red shoulders or greens and I thought it was a red severum thing
I always threw some salt in and it would go away for a while and now and then come back again.
Will be interesting to see what others say
