Tucked into a plaza on Route 28 in Windham, New Hampshire, The Aquarium Gallery is the kind of fish store that turns a quick errand into a two-hour conversation about the hobby. Owner William has decades of experience and a genuine passion that permeates every corner of the shop — from the crystal-clear tanks to the impressive vintage aquarium collection that gives the place a museum-like character you won't find anywhere else in southern New Hampshire. The freshwater selection is the store's backbone, and it goes well beyond the usual goldfish and guppies.
Locally bred fish are a point of pride here — reviewers have picked up apistogramma honsloi dwarf cichlids, white cloud mountain minnows, and species they couldn't track down at any other shop in the region. The live plant section is genuinely remarkable, with healthy, thriving specimens and staff who will walk you through planting and maintenance step by step. One customer even walked out with a free pothos cutting for their tank.
Saltwater is a growing part of the inventory, with corals, live rock, and a selection that William appears to be steadily expanding. The store also stocks quality driftwood, aquascaping materials, and supplies — no need to piece together an order from multiple sources. William has worked with Quantum Technology on custom aquarium pieces for the showroom, and he'll help customers source complete end-to-end setups within budget and on tight timelines.
Staff members Krystian and William consistently earn praise for patience and genuine helpfulness. They'd rather understand your full water chemistry picture before recommending a product than toss a bottle of conditioner at you. Multiple reviewers note they were steered toward what would actually succeed in their tanks rather than pushed toward a sale.
The display tanks double as inspiration — a female koi betta thriving in a lush planted setup caught more than one visitor's eye. People drive from Massachusetts's North Shore and beyond, and they keep coming back. That says everything.

Great customer service. On the hunt for an assassin snail . I was happily educated and informed they could order and help me find some more residents for my tank that would be a good fit when I pick him up

Drove up from the north shore of ma to check out the shop. Nice set up, reasonable prices and some really cool vintage fish tank collectibles. Will, the owner, was super helpful and patient with us while our little one popped around store and even had some stuffed fish plushies for her to play with. Good selection of fresh water fish and plants and it looks like they are buffing up their saltwater selection too. Will definitely be back! Thanks again Will

Huge thanks to William. My husband and son got stuck with a flat tire and pulled into the plaza late tonight. William came out with tools, and WD40 to help put on the spare. Nice reminder that there are good people in the world!

I was looking for some plants and heard this was the place to go. The plant selection is incredible, never seen anything like it. William the owner is great to talk with, he's super friendly and knowledgeable. The fish tanks are all gorgeous with a great selection of healthy fish. He's got a very cool collection of vintage tanks as well! Worth the drive from wherever you're coming from.

Went back here for a second time today! Both times had great service and advice both from Krystian and William the owner. They gave me great advice each time and both were very knowledgeable. They helped me with every request I had and offered advice to my first time tank owner self! I highly recommend going to this aquatics store if you want great help and guidance! Pushed success for my tank, not a sale. Thank you very much! Will definitely be back!

I have been speaking with William at The Aquarium Gallery for a couple of months and working with him to select the pieces he purchased from Quantum Technology for his show room. He was such a pleasure to speak and work with and he is VERY professional, pleasant, knowledgeable and communicative. I experienced an exceptional level of customer service. William went above and beyond to explain his business and the product he was looking for which made my job easy. If anyone is looking for a custom aquarium provider I would highly recommend contacting William.
