Not the same genus (Caridina v Neocardina), but yes, both of those products are safe with inverts. That's not to say the shrimp will have all their needs met, of course, but they shouldn't have a problem with either of those products.

There are a couple. KnockOut Aquatics off 611 is great--the owner is a hobbyist, started a business to sell the frags from his own reef tank, and a little over a year ago, moved to a new building and expanded to include FW. The FW side is still developing, but he's got great prices and good stock.

Ultra is up the road a bit, and even newer to the FW scene. They have lots of really nice corals, but are pricey. I haven't been in to see anything more on the FW side, just knew they were expanding.

If you're into angels or fancy guppies, City of Angelfish is nice. They breed and sell angels and have an expanding selection of cichlids and cories.

Not really in the Poconos, but Something Fishy is top notch for SW.

Also in the LHV, American Aquarium is nice. Less SW, but if you're in the market for a used tank or looking to get rid of one, they buy/sell for reasonable prices.

But tbh, I haven't bought a fish from any of them. Most of the fish in my tanks have come from Rachel or from an auction at one of the local fish clubs.
