Need Help!!

[reef-junkie]

Recently purchased an 8" snowflake eel. Since the moment he was introduced he has been violently twitching his head. Eel resides in a 65 gallon tank, temp was a little higher today 80f. (corrected this) salinity is .024. no nitrites or nitrates. Introduced a valentini puffer at the same time (puffer is doing fine and these are the only 2 occupants)
The eel is accepting food which is good. Has ate both shrimp and squid so far.
Will this go away with time? Is there something I can/should do?

Any help would greatly be appreciated!!!
