Its not always trusting your LFS that is the issue. Wholesalers have been known to deceive the LFS. Especially when it comes to the finer differences in tank raised, captive bred, pen raised, etc. It can be labelled captive bred and still have been raised in an ocean pen or in tanks circulated through the ocean. It can still be labelled tank raised if it was wild caught and then raised in a tank. You want it both captive bred and raised in a closed system. Thats usually why we recommend the aquaculture sites where they are bred, raised, and sold from the same place. However, if you have observed the seahorses for several weeks in the LFS and they still appear healthy, and you know for sure what species you are getting, and they haven't added any new seahorses or pipefish to their system since you began observing your horses, and they are eating frozen mysis (not frozen brine - that would indicate malnourishment and unhealthy horses) then I see no reason why you shouldn't purchase them. Lots of "and"s, huh?
