I visited this shop yesterday for the first time and immediately knew where I was coming to stock the rest of my tank, and I live 1 1/2 hours away. The staff was very knowledgeable about everything in the store. The place was also incredibly welcoming. One thing I enjoy is a place that I look forward to going back too and this is absolutely that place. So if youre looking to get into the hobby I couldnt recommend Mile High Tides more.

Jake is simply awesome!I contacted Jake about moving a tank to a new house and his rates were extremely reasonable and I was blown away by his process. It was fast, clean, and very cool to see him work. I learned a lot by helping out. Jake is by far the most accommodating person in this business I have met by far. His schedule was jammed pack between setting up his shop with new tanks, a partnership merging, and his store anniversary! He MADE the time to stick to his word and personally help me out. Just an awesome guy who loves the hobby and helping the hobbyists succeed.

I give these guys 5/5. They are local and independent. Their selection of coral and fish is astonishing! Especially for how long theyve been open. I highly recommend checking these guys out

This shop is awesome! Very friendly crew Jakes awesome today, I checked it out for the first time. I definitely recommend it. I left with a free 4 gal starfire tank on black friday for a doorbuster gift So rad. I picked up a couple of really cool fish also and great pricing so stoked on these guys I will definitely be back soon

Jake and his crew were super helpful. Awesome shop and great prices on the corals which are top notch! Definitely my new spot

Just stopped in at this fantastic new store, and picked up a beautiful torch... Huge selection of coral, and at great prices. Large, clean store and, most importantly, immaculate tanks. The owner is very friendly, and extremely knowledgeable. Definitely excited to have a new go-to shop for saltwater because, as we all know, the good ones are hard to find. Thank you much!

I love this place. Clean, modern, great selection and great staff. They even special ordered my fish.

Great facility! The owner Jake is amazing and he really took the time to show us and chat. Super amazing people, and I will be back regularly to what tank dank I can take home!

People seem cool, but this place is joke.I went in on Saturday (Support Small Business Day). I asked about specials and tall guy with glasses tells me it is 20% off storewide. So I decide to buy some fish. Two wrasses, a blenny, and a goby. He bagged blue sided wrasse and goby right away. The blue sided wrasse was in same tank as blenny. The blenny would not come out of rock. I ended up waiting an hour even though I told them they could catch him later and I would come back. Instead they gave me the rock with blenny in it. Jake was cautious and said the tank was treated with copper so let me know not to put it in display. At check out everything rang up at full price, I said what about 20% off? Jake said it was only on frag tank but he would give me 10%.I get home and acclimate fish. The blue wrasse was not doing well the whole time and flukes/fish scales were falling off of him while still in acclimating. All fish went into qt tank. All other fish were fine in am, even blenny which never left rock. Blue wrasse was dead in the am. Within 24 hrs, I was back at store with dead fish. Tall guy is sitting down and says they don’t warranty marine fish. He claims neither do other fish stores, which is not true. I told him fish was not well during acclimation and his reply was that I should have called the store and told them!!!! Anyone with experience acclimating a fish knows each fish acclimates differently. So he refuses to provide a store credit (around $36, not a big deal to me).I know Jake, the owner, is highly respected in the fish community, but this isn’t a way to do business. Have employees tell a customer that there is a storewide sale when there isn’t. Have a customer wait an hour+ to catch a fish when customer said just catch it later and he will come back. Give customer a fish burrowed in rock treated with copper. Don’t even warranty a fish that dies within hours of being acclimated and qt. The tall guy didn’t even have the courtesy to stand up when customers enters the store.See FB review posts from 11/29/2020. All they do is give excuses and blame others. They even blame the time of my purchase on someone else. When you know better, you do better.

A really great new reef shop. Great selection of imported and aquaculture frags. The guys working there are very knowledgeable and clearly passionate about the hobby. Definitely worth stopping in!
