Yeah quite a few but some are a bit pricey ay fish tank at castle hill is pretty good really nice corals and better on price another one at auburn they sell frags as well for around $30 but personally I think that's a bit steep
The one at auburn can't remember the name of the place but it's right next door to parra and homebush closest one to the city that I know of but on a serious note check out marinefishdirect.com at narreallen they have good prices on corals and fish and i know they give good price on delivery so it might save u the trouble
But auburn and castle hill are the best I know of don't get around the other side much and don't even bother wit the the one at Windsor the web site is miss leading don't even bother it's not good
