I was under the impression that fish lack the CNS required to "feel pain" and as far as salty nets a pet store owner taught me years ago that doing a saltwater dip on new fish kills parasites that are stowaways on the fish when delivered from his distributors vice versa for saltwater fish..... Anyone?
I've known about the practice of dipping saltwater fish in freshwater for a few minutes to rid them of any parasites they might have,and I have done it in the past but is very stressful to the fish.I don't recall hearing too much about vice versa though and that I've never done.
Might be kind of moot but do they actually tattoo the fish in the store or do they come in that way?
