If you're on the East Coast and can make it out for a weekend, it should be well worth it for the plant geeks - 2 of the talks are plant-centric (demo and Jason's talk on photography should have lots of nice plant pics), there will be the GWAPA group with a huge presence there, and the auction should have a lot of plants, including the rare stuff from the local guys. You will have plant talk coming out of your ears!
There are also several vendors coming that you can special order from and get delivery at the convention. I know at least two are posting plants at their sites/mailing lists, in addition to rare plecos, imported fish species, apistos and angels, and all sorts of other things.
aquafest2009.org for a vendor listing, they should al be linked to their sites off the Aquafest site.
Next weekend is the day! Still undecided about coming? Check out what ADG sent us for the aquascaping demo! The will be fully scaped, there are 2 one for raffle and 1 for a silent auction. Both complete with Catalina T-5 lights, fully scaped, and canister filter. All you will need it CO2! Awesome!
