I made the mistake of going in my local PetSmart for some cat food. Of course, I had to see the fish and fell in love with two oranda's. I had a 40 gallon breeder ready for some ranchu but here I am with oranda's. The calico oranda has a curled gill cover. The aquarium has been treated with Prime and aquarium salt. I plan to treat with Prazi Pro tomorrow. Could this just be a fluke? He seems healthy otherwise and is very energetic.
