I am in Westchester, NY- 10549/
I am not a fan of Beitals. I paid them good money for a large clown loach that turned out to be not healthy with internal issues- bad result. They are rude, overpriced and it is an unpleasant experience being there. I will not go back.
I have been to a few excellent stores. But I mostly buy from breeders, wholesale or imports. I also buy at my aquarium club meetings.
Shameless plug: If you are interested in the B&W Hypancisrtus from the Rio Xingu. I breed zebras, L236 including superwhites and L173. I allow pick ups and charge less when I do not have to ship
There is a pricey but excellent fish store in Greenwich, CT. To work there you have to pass a test re fish. They really know their stuff which helps. But you pay for what you get and they are not cheap. It is actually one of the few stores from which I may get fish which I do not always Quarantine. That is saying a lot for me.
I was sorry to see the Shark Aquarium in NJ close.
