Water temp is 58F. The fish are from Tasmania (all but one anyway)....the inverts are from Puget Sound (except for a couple of stars). There's really way too many critters in there to research and find scientic names.....since no common names exist like in warm water it becomes a long research task....sorry..... but, If there is something in particular that you want to know....I can find that out for you....but, I've never been a stock list guy.
