Today I got my CUC order from reef cleaners. Ordered over 200 snails, a boring rock urchin, and a porcelain crab. I acclimated, then put everything into the tank. Within 2 hours, my fish started acting strange and darting around the tank unexpectedly. All fish in my tank are flashing uncontrollably, and darting from side to side. I don’t have ich, or any other parasites... Then i noticed my sailfin has a massive black infection, almost like an ink splatter all over his skin. Is it possible that reef cleaners leached something into my tank? Or maybe his got stung by the new urchin? Does anyone have a clue what this maybe?
