What do you do with kids on an extra cold night? Let's go to the aquarium that we have yet to visit…read moredespite living in Denver for ages now. Due to the cold, no lines for tickets. Great indoor activity. Fairly empty inside. Perfect evening. Prices are steep for parking and admission. It's a one and done activity for us. But it was worth the experience! We spent almost two hours there, taking our time to admire and learn. We really enjoyed seeing all the beautiful sea creatures - all varieties of fish large and small, sharks, jellyfish, stingrays (which you can pet at the end), two random tigers (not expecting that at an aquarium), turtles, snakes, lizards, frogs, etc. Only negative from our outing was the guy in the ticket booth. We brought out of town friends with us and it was freezing outside. He could see that we had kids and were all super cold. It would've been kind if he had said we could just go inside and wait for the husbands to come in with the wrist bands. As it turns out we just ran inside anyway to wait for them, but not very good customer service.

After I left, an employee actually came outside to demand that I return and pay more. This is completely unacceptable and shows a shocking level of incompetence and poor customer service.

I can't say enough good things about this fish store and the incredible people who work there. When…read moremy tank unexpectedly sprang a leak, I was completely overwhelmed and stressed. It felt like everything was happening at once -- and I truly needed guidance, reassurance, and kindness in that moment. Love was absolutely amazing. Not only knowledgeable, but genuinely compassionate and patient. I never once felt rushed or dismissed -- just supported. Rumi also went above and beyond, answering my emails almost instantly and making sure I had the information I needed right away. That level of responsiveness made all the difference during a stressful situation. What could have been a total disaster turned into a reminder that there are still businesses that truly care about their customers. Their kindness, expertise, and willingness to help meant more to me than I can express. If you're looking for a fish store that treats you like family and stands by you when things go wrong, this is the place. I'm incredibly grateful. They've also given me piece of mind for my future vacations

Zero if I could. What an awful experience. The CO owner lied to me, she told me she could work with…read moreme on a dead fish, I should've known that it was too good to be true. Having driven 45 minutes to the store with my water sample, which I tested against test strips, don't buy those, I was told the phosphates were too high. They don't include phosphates as a red flag unless they're going to deny you. My nitrate was too high? Nitrate is a normal part of a tank cycle. I've never qualified buying new fish based on having to do a tank change the day before purchase. And phosphate! Serious? Do you even sell that test kit? I've never seen it before. After spending $500 in one week you could do me the courtesy of saying "bring a water sample, it doesn't matter we're not giving you a thing." Notes: they are super friendly and helpful when you're buying something. Just don't expect much. They had a dead fish in one of the tanks that my son pointed out that had been there for at least a day. At least that's what the pleco was thinking. Now, find the tank. They have a 48 hour doa policy. They won't budge, trust me. Ask my seven year old who spent $35 on a butterfly pleco only to have it die within a week. $17.50 would have been enough for me, more than fair I said. Finally, even if you live in Elizabeth or Parker, and you are five minutes away from the store, drive the extra 45 minutes to Wheat Ridge and go to The Fish Den. Tell Michael Jason sent you. They have a better rating than MC Aquatics. Here are my readings according to an API freshwater master test kit ($40 at petsmart) Ph 7.4 High range pH 7.8 Ammonia 0 ppm Nitrate 0 ppm Nitrite 0 ppm See the pic below. Finally Phosphates: that's a joke. Good luck knowing that. You're welcome. Next time you tell someone nitrate is a 39, make sure that you tell them what the safe range is. And to think, you guys normally charge $6.00 for a water check. Buy your own test kit and save yourself the headache. Date of incident, June 17, 2025 Water sample from the same day.
