ready for another shock?....99% of cichlids breed in s.e.asia are infected with HIH.
it all depends on your water condition. bad water condition usually encourage bacteria outbreak which leads to late stage HIH...pimples brusting, bacteria eating thru the wounds to create the infamous hole.
larger cichlids usually will survive the infection...for example take a close look at an adult oscar...tell me wat u see.
if the fish survive the first attack...its immune system will develop a resistant to it...but the scar will remain forever.
no such luck with smaller cichlids...they seldom survive the first outbreak.
so care must be taken on your water condition to prevent outbreaks.
uneaten food ...is the source of this outbreak. dun overfeed...remember
