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.

I was incorrectly sold a fish. So I started my fish hobby journey about a year ago. I currently…read morehave a 60 gallon community tank with dwarf neon tetras, Congo tetras, Cory's, BNP, petricola, khulis and a few Amano shrimp. Unfortunately I trusted the advice given to me by Jacob and I purchased a flower horn blue polar parrot hybrid juvenile. When I got home and did some more research I realized how unfit my tank is for this type of fish. It has already began eating the fins off of my long fin Cory's and it is also going after the Khuli loaches. I now have to rush around and try to find a different home for this fish. Extremely disappointed. I would not recommend going here unless you know what you are looking for and you know not to take their advice cause they are only trying to sell you fish you don't need can't provide for. I feel extremely taken advantage of.

We browsed around for a bit before finding cute, affordable fish. Cherry Barbs and Bleeding Heart Tetras. I was hesitant to ask questions after being scolded by and shunned by a different store but the guy there was very helpful, informative and inclusive. I didn't feel like I was being preached to. We left with 5 fish and some bacteria stuff. 6 days later and they still seem happy and healthy. We will be going back in the future. Good selection that ranges between cheap fish and very expensive creatures, friendly staff and convenient location. Highly recommend.

Fins Up is hands down the best saltwater aquarium store and service team I've ever worked with…read more Their prices are more than fair often better than what you'll find online and they back it up with an incredible depth of knowledge about saltwater systems, corals, and fish care. What really stands out is their customer service. The staff takes the time to explain everything, from equipment recommendations to proper tank maintenance, so you feel confident and supported. Their tank service is top-notch as well professional, reliable, and it always leaves my setup looking healthier and running smoother than before. Whether you're a beginner starting your first reef tank or an experienced aquarist looking for quality livestock and expert help, Fins Up is the place to go. I wouldn't trust my tank with anyone else.

Ryan and his family just opened up this gem of a reef and fish store and I speak highly enough of…read moreit. They carry most of the brands us hobbyists know and love, as well as brands that are comparable in quality, but lesser known and lower priced. The prices on coral and livestock are really good. So much so, that I drive from north Thornton, passing at least 5 closer fish stores, to their store to get what I need. Ryan runs an amazing service program as well and he helped me turn my tank around in 2 months when I thought it would take at least a year. I'm telling everyone I know about their store because the service, products and attention to detail are second to none!

I really love this store. The fish are healthy, & the lady running the shop has a wealth of…read moreinformation that she freely gives as she shows you her fish. You can tell she loves the fish and wants them to do well with whoever they go home with. I was mostly focused on getting some fancy goldfish. Orandas, Ranchu, Ryukins, some of the more extreme body shapes. She had plenty and I purchased 4. It's been 2 months of beautiful & happy fish. I worked in the aquarium & fish business 30 years back for most of my 20's. I had always wanted a shop of my own. But the overhead cost of caring for, feeding and housing before you ever sell a fish make this a difficult business to survive in. But, its the only way to assure your selling healthy fish. So, when I find a shop like this, I support that shop, and I spend my money there. So, the shops like this, that sell the happy healthy fish, and give you the info needed to keep them that way, are able to continue to do so for years.

I placed an online order because they had freshwater eels for sale I have had aquariums for 60…read moreyears The eel was $19 To make the $60 dollars of packing and shipping worthwhile I placed a $300 order including some live bearers As is standard I ordered 3 to ensure 1 male and 2 females On the check out page there was a place for shipping notes routing insurance was added to the invoice with no option to remove it and no link to be able to read the insurance info so my assumption was this was added so that the shipper could replace dead fish They called me before shipping because one of the fish I ordered had Ich So we spent an hour on the phone deciding on a substitution The packaging seemed good when I first opened it as I unpacked the fish I noticed the eel had been packed in a bag that was the same length as the eel and it was dead Eels are fickle Any stress and they die to pack an eel for shipment with no wiggle room was bad and he died Other bags had leaked and barely had enough water to cover the fish I had to open the leaking bags and combine fish from two bags into one so there would be more water for acclimation Then I noticed that they had sent all females for all the live bearing fish Something that a professional should know not to do And it was apparent that the pictures online had been color enhanced because the actual fish received did not have the intense coloring displayed in their pics Had they been honest about what the fish actually look like my order would have been completely different if I had known they were going to unload all females I would not have ordered them because they look like ditch minnows I spoke to a manager and told him about all things listed but mainly because the one fish that prompted a $300 order was dead due to either sick stock or improper packaging and the shop bears the responsibility The manager said I should have specified the sexes of the fish but there was no place on the fish page to choose the sexes even though there was a drop down menu to select size and to choose quantity the only place I saw where notes could be typed was in shipping instructions Besides these are supposed to be professionals When I pressed the manager on this he admitted that when people buy in the store they are asked what sex they want the fish to be I was on the phone for an hour with the guy to make a substitution for a sick fish and that was plenty of time to ask that simple question They also informed me that I would have to pay shipping and packaging again for them to replace the eel with no guarantee it will arrive alive. when I asked about the insurance they had forced me to buy they told me that I would have to contact the insurance carrier and file a claim and even then they probably wouldn't cover the shipping I told them that they should be the one to do all that is necessary to replace the dead eel that died in transit because that is what customer service is Shipping is the responsibility of the shipper I honestly thought the forced insurance on the checkout was so the shipper could cover these kinds of issues Especially since there was no link to review the terms and conditions of the policy And there was no place to unselect the insurance The manager could not explain to me why there was a forced insurance purchase if it didn't cover dead fish their online ordering is a scam They deceive with color enhanced pics, unload excess female fish by not having a place to select the sex, they force you to buy insurance that has no benefit to you if the fish arrive dead, and they deflect blame When I sent an email detailing all this, the owner replied and said that their policy stands I have scoured the website and I cannot find any information that tells the online ordering customers that they will not honor replacing dead fish even if they perform poor packaging or send dead or dying stock They kept telling me they were a small store and couldn't afford to absorb replacement costs for dead fish. Then don't sell online!!!! Or actually purchase insurance to cover replacements including shipping Out of curiosity I went to the post office and the UPS store near my house and asked them the overnight shipping cost for the box they sent with water in all the bags and it was half what they charged for shipping costs Keep in mind they charged $15 for all the packaging material DON'T ORDER FROM THIS STORE Shop at your local store this company is a scam by using bait and switch tactics with pics, offloading undesirable female live bearers, poorly packaging the fish, forcing the purchase of useless insurance, and deflecting blame back onto the customer I asked how this would be if I paid the $60 shipping and packaging for the eel to be replaced and it also arrived dead they had no answer They may be nice in person but they have no problem cheating online customers
