i have kept lions sinse the beginning of this hobby4 1/2 yrs
not many typesof fish i dont keep or should i say catigories of them.question is to you ckehl before treatment for the paresite be 100% sure it is ich .spots are not as easily seen on lions as many other fish are due to its coloration and paterns.ich canbe more seen on the eyes of a lion at least if its a volitan russels or clear fins may prove to be easier.is the fish still eating ,acting shy , stressed by other fish ect.as an agressive speecies this fish does not tolerate harassments of any sorts .if you have a lion ad suspect ich or other problems feel free to ask questions reguarding what can be done for him
