Morning,
Just woke up this morning and did my usual check on the fish only to find one of the fish has a louse attached to his dorsal fin, unmistakable disc-shaped louse with moving legs, kind of green in colour - this may also explain why one of my other Oranda's has been kind of "off colour" for a couple of days.
I have been frantically looking up treatments this morning, I see Interpet do an Anti-Crustacean treatment (No.12) but this kills off the biological filter - as this is the only aquarium in my house I have no practical way of moving the filter & keeping the bacteria alive while I treat the tank and all of the inhabitants.
Does anyone know of any lice / parasite treatment that doesn't affect the biological filter OR know of a method where I could move the filter out and keep the bacteria alive for seven days while I treat the whole tank and the fish? I don't want to have to start the biological filter again from scratch especially when we're talking about 8 fancies in a 600l tank, far too risky in my opinion.
Thoughts would be greatly appreciated.
