nope that the point of buy LR and LS istead of just rock and sand. it's ALIVE!
do you wan to do inverts/corals?
if you do talk to someone else, i haven't gotten into that yet, fish first.
depending on what you like youve got some options (why 10gal?)
a single damsel of your choosing. i'd stay away from the larger ones domino, garabaldi (if you could ever find one!)
a single clown or mated pair of the smaller variety ocellarus/percula
almost any kind of goby or blenny just don't get a scooter blenny or mandarin fish (they need really specifi things that are hard to find in a 10gal)
uh..... firefish but they usually like groups
dottybacks
smaller, fairy wrasses maybe
alone hawkfish
grammas and basslets
or you could just do a reef scene with some shrimp snails and hardy corals. i wouldn't do any anemones because they get really big and would easily and quickly outgrow a 10gal.
