that happens all the time in big name stores. it has to do with the tax paperwork.
now you dont typically get that at a local fish store as their stock is not tracked and also they tend to take in or trade stuff more often.
right now i have a 6-line wrasse i rescued from the lfs. its got a curved spine but it gets along with everything and its in a mostly coral tank.
jay if you lived around me id give you a 10 gallon or 2.
currently i have 9 aquariums running 2 of them are saltwater
