They're now open, Lots of marine fish and inverts at what appeared to be reasonable prices.
They also have corals but I was there early and the lights weren't all on yet so I can't really judge quality, but prices also seemed reasonable.
A lot of captive propagated livestock and pretty well stocked with hardgoods too.
There's also a freshwater and planted section, but it appears to be primarily a reef store.
Lost Reef is in South Venice, not to be confused with Father Fish which is the old Puss and Pets store south of Venice Ave.
