I keep hearing good things about Sea Dreams, I was planning to take a trip down there but this fricken ice storm knocked out my power for 5 days. And now we have a good amount of snow on the ground. Will have to wait till after christmas most likely.
Manhattan Aquarium Supply is junk, the owner is knowledgeable but he is very very rude to customers. Pets N Stuff doesn't really have a great selection of fish, and they aren't very experienced in that field as well. Seems like out of town is the way to go.
Scaley Daves would be awesome if they carried more fish stuff, which I have heard will hopefully be soon.
