Of course there's always the option of collecting them yourself IF you can recognize what you're catching, wouldn't want to get anything that get big or is on any watch/endangered list. Fish shouldn't be released after being moved to captivity, even back to where they were collected. I went when the NANFA convention was here so I didn't have to worry about collecting something that wasn't compatable with my situation or was on a watch/endangered list.
