This place is set up like your older brother's fish room... organized chaos... lol, but everything has its place. However the staff are very friendly... and the fish quality can be rated from 4.0 to 5.0... very high indeed. The prices are also unbeatable in today's small retail trade. There is a big sign posted above the entrance off of Northern Blvd... the actual entrance is a staircase to the left that heads to a basement level. Take the stairs and turn to your right ... and walk into the above mentioned fish paradise. They have a wide selection of all interests and again the quality is high as there were no dead fish in the tanks ( I spent an hour going from tank to tank) and the overall maintenance appeared quite high. All in all they deserve and get a five star rating from me. The staff are never intrusive but are there to answer any questions. As an experienced aquarist I prefer to be left alone until I have a question or am making a purchase. They have the right mix there at KHC. This is one of three stores in Queens and Nassau that are now my go to stores. Lastly, they will try to fulfill exotic fish orders as well. They also give advice to the level of the customer, without talking down to the inexperienced as I have witnessed. They love to have serious,fun and genuine conversations about fish.
