Josie Smoesie

It’s hard to find saltwater stores that’s close to home so I was happy to find this place. The tanks were nice and clean. Their display tanks look gorgeous. Had a nice mix of coral and fish. Everyone there was friendly and knowledgeable. We didn’t feel like we were wasting their time with our questions. Got a Skunk cleaner shrimp from them weeks ago and it has been a nice addition to my tank. Would highly recommend.

These guys are great! I absolutely love thier business mindset. I have freshwater tanks, but this store is exclusively salt water. I'd love to do a saltwater set up someday. They took awhile sharing about saltwater set up and were happy to answer questions. It seems like they have high quality products and friendly staff. They carry supplies, fish, corral, tanks, and saltwater (I think).

We spent years making g a wonderful 45 gallons salt water tank and then we wanted a bigger tank so we Upgraded from a 45 to 120 gallons tank. We had them set it up and move everything. Extremely professional, meticulous, and knowledgeable. They made sure the fish were happy and we were happy. Done in a day and everything is as healthy or more. Highly recommended. Exceptional pricing for the services provided.

Wow, what a cool store. Knowledgeable staff at this family owned Coral Reef Tank store. I walked in expecting to see an average collection of saltwater and fresh water fish, and instead discovered a huge menagerie of Coral "frags" and colonies. A beautiful selection encapsulating the rainbow. Michael talks about the hobby of "reef tanking" with a passion that shows he loves what he does. I purchased a tank, and the owner came by himself to help with the install. They brought everything out that we needed, including the water for the tank! We love our new tank, and the family is excited for it to complete the bacteria cycle so we can head to Biggs to select our first corals and fish.

Amazing family ran store! Clean tanks, great coral. Small fish selection, but great fish and healthy. I don't mind the hour+ drive every time I go up. Will continue to support the biggs team!
