Yes he is still alive and he is the meanest ******* EVER
That is odd. Well, at least you got the fish you ordered. I've heard that about the Achilles personality. Is it in quarantine with other fish? I've never owned one myself. I don't mind a bit of chasing or a fish protecting its home, but I prefer a semi-peaceful tank. I tend to get upset when a fish is picked on relentlessly. LOL
