The many varieties of exotic fish at Pacific Aquarium and Planet, in the Lower East Side, are the focus of the stock and attention of the staff. It’s not unheard of for sales to customers to be denied for lacking the proper equipment to support some of the very sensitive, exotic species. Both fresh and salt water fish are available, including Japanese koi, cichlids, arowanas, praecox rainbows, cardinals and even stingrays. Believing environment is just as important as water quality and filtration systems, the shop sells live coral and aquatic plants like Riccia, Java Moss and Glossostigma. The regular maintenance service is also strongly recommended to newbies of exotic fish collecting.
