that isnt true. perhaps the place you read it from were only selling tank raised ones. many of the false percs in the hobby are tank raised because they are so easy to breed and there are so many breeders around, they are easy to get their hands on.IF false perculas are only tank raised, then what happens when they are released into the wild? Do they magically change species? (read this off somewhere)
but there are wild ocellaris clownfish
