I hope this is okay to post here (Im new). Just wondering if I can safely mix (after quarantine) ECR fish with fish from King Koi and Goldfish? I know that ECR fish come from near sterile environments and KKG fish are imported fish, but KKG fish go through several rounds of meds during their quarantine period. So would it be safe to have them in the same aquarium or does this mean I will have to buy another aquarium? xD Thanks!
