Have you guys noticed also, how LFS have very very beautiful cardinals on display at the front of their shops then after few months you will notice that there cardinals have also all disappeared due to sickness. ... |
This is mycobacteria disease
The flesh turns off colour( this pale spot usually stays about same size & can be any part of the body ) & fish slowly wastes away/doesn't eat & finally dies very thin : like discus when they turn black
Common in many types of guppies & feeders too
Suggest quarantine & treat with antibiotics before mixing
My lot of Gan's cardinals don't seem to hv this disease
