If you were to buy that I would pay a full deposit (if u trust them) but ask them to 1) put it in a larger tank as it is probably stressed in there. 2) fatten it up and see it feed over a few weeks 3) ask them to worm it and do a parasite session.
Pick it up in 3 weeks to a month if still alive and fatter.
