Amazing shop and great service! Healthy fish and corals. Highly recommend.

  Very knowledgeable! Been to the store several times and built an amazing community tank from here. Called on several occasions with urgent matters and the staff is always ready to help over the phone. I live in the other side of the state but would rather spend my money here than anywhere else!

  Do not remember who helped me he does their YouTube channel. Had such a warm welcome and got great help picking coral for a beginner and it was free frag weekend, what a great way to motivate a brand new reefer! 100000% will be going back here!

  Love this place. Staff welcoming and willing and able to answer questions and provide knowledge.

  Absolutely stunning display rooms filled with a wide variety of corals/fish and equipment. The staff was welcoming and very insightful I will be going back again.

  Had a complete disaster with my 220. Bottom blew out and tank was quickly draining. I left a frantic message for Scott, got an immediate call back, and he quickly responded with a crew. They quickly and calmly managed a reefers worst nightmare. Seriously folks...Scott and his team are the best. I buy my corals and supplies from them, they completely replumbed my system and added a mixing station, and now showed how they handle a major reefing emergency with speed and professionalism. No better company in this industry then OSA.

  Everyone who works here is beyond awesome. As a beginner to saltwater, OSA is my only place I go to and trust with questions. Corals and fish they have always look beautiful and healthy and are very reasonably priced. No question I have is too silly and trust me,I ask a lot of them lol. I'm glad I live so close by but even if I didn't,this place is SO worth the drive if you're considering it!

  This store is so good I had to give them a second review. My last review from Fannypack_hater was my first, but this store honestly is the best store I go to and keep going too. #1, the staff are 100% nice, don’t bug you or watch you when you walk around, they tell the truth, if a fish will grow big or kill another fish, they will tell you not to get it. I have never gone to a fish store that has done this, the other part is, there prices are unbeatable. A 4” bounce mushroom for $400, that’s a deal! I would and have been recommending this place to any reef keeper or people starting. That’s why it deserved a second review!

  Absolutely the best . I have been going there for about a year and purchased a ton of corals. They have a huge selection and at reasonable prices. I also had my 220 reef tank completely re-plumbed after a nameless company botched it. It was a first class installation done by Scott and Pat. On top of their huge selection and top notch service and installation, they are genuinely nice people. They are worth the trip and you will be hard pressed to find a better company with nicer people. Thank you Scott and Pat Steve Goyette (and his happy wife...now)

  Best coral selection in RI. I have purchased several corals and invertebrates from them (last year). Nice prices and nice selection. Very knowledgeable staff. UPDATE: 9/11/18 Fantastic store and service! They upgraded me from an old reef to a brand new Waterbox 100.3 in August. Love it! Great customer service and unbelievably nice shop and selection. Well worth the trip from long distances to see their selection of corals. (Fortunately, I live close by.)
