well i'll tell u ... i have seen lympho many times, but only on larger angels ... i ran the skimmer on the system for three days anddid a large water change after and haven;t added any more copper, the copper levels are now undetectable ... upon the water change i redosed prazi and added kanamyacin incase the fungus was a symptom of a bacterial infection ... the 'fungus' has began to be depleted on the maculosis ... but this similar experience is on a show size personifer i did not post a picture of; the striated nature of the fungus led me to believe it wasnt clumpy lympho .... but the maculosis has begun to look better, personifer no ... is it the kana treating the bacteria or the lack of copper reducing the stress of the angel, reducing the lympho ... all my angels get lympho during copper treatments ... still very questionable ...
