First I want to point out to Nikolai that if done in a humane way, catching juvies in the wild and putting them into a large, well-maintained tank is in not cruel. Even many of the commercial fishermen who are catching them for the lfs's are being much more humane and going through proper decompression measures, etc., than ever before. More than 50-60% of fish in an lfs are wild caught unless they are associated with a large breeding facility, which most are NOT. In addition, MANY SW fish still do not breed in captivity, therefore, where else would they come from? And I have seen the condition of the reefs out there very recently. NOT a pretty site.
Second, I agree with Ophiura about not returning them to the wild. Aside from the parasite issue, they adapt very well to being well fed and may not re-acclimate very well to living in the wild again.
And what Fishnerd said is also true. Under the Blue Heron bridge I have seen at least 3 to 4 kinds of shrimp, a HUGE lobster, fish all over the place, sea cukes, crabs, all sorts of critters. BUT, it can be a NASTY current so check the tide charts before planning the trip. Also, if you see a light green fin just hangin around, give me a yell, I lost it there about a year ago.
They were my favorite pair!
