Coral Oasis of Costa Mesa is owned by Ben Luong (previously in Irvine six plus years ago)
Very good store for softies and LPS at a good price (decent size corals too, not this dime sized crap that some retailers sell)
Coral Oasis is right off the 405 freeway at Fairview:
Coral Oasis
2959 Fairview Avenue
Costa Mesa, CA 92626
(714) 957-2993
Just a word of advice:
Many times its a non-hobbyist family member watching the store (just a matter of economics) so don't get all riled up if they are not the most knowledgable on everything. The person with the experience should be "You".
