Hello i have 4 pink convict cichalids who have developed black spots on their bodies;possibly on the fins aswell. After doing research, black ich seemed likely so i got prazipro to treat, i have 60 gal and treated as accordingly, its been 4 days since initial treatment and the black spots seem to have stayed/ possibly more have surfaced. Can anyone help confirm if this indeed is black ich? Or is it some type of bacterial infection? They are all active and eating well, 1 has sunken belly and the others are slowly developing it. I first noticed the black spot on only one a month or 2 back but did not think anything of it (silly).
