We have had a Copperband Butterfly fish and a Midas Blenny in quarantine for a month. They have never had spots or anything visible on them this entire time. On day 3 of them being in qt we saw Copperband itch so we started treating with Kick Ich and Rally and are still dosing Kick Ich while using Rally intermittently per both instructions. Copperband still itches once in a while, still no spots. Do some fish just itch sometimes? We’ve used these 2 Ruby Reef products before to treat ich, bacterial infection etc and have always had success so we know they work and that together they cover a broad variety of fish illness/issues including flukes, velvet, brook etc. Any thoughts on why this guy still itches sometimes? We’ve seen our 2 wrasse in one of our other tanks itch once in a great while, but there’s no disease in the other tanks. Everything goes through quarantine.
