Sleeper Head Gobies

[idgy]

Just got a delivery from Vivid Aquariums, ordered two sleeper heads, sadly one arrived dead. Will the one be OK on its own or does he or she need a mate and can I add another one within the next couple of days without any trouble.

Thanks.

u should be OK if added later....how big is the tank? two main causes of deaths: 1. notorius jumpers so a tight sealed lid is required, 2. does not eat prepared food and dies of starvation...if you can get them to eat mysis shrimp or sometype of meaty food, you are golden.
