Walking into FantaSEA Aquariums in Crofton, Maryland, you immediately notice the difference between a typical fish store and a business built around saltwater obsession. The facility is spotless, the display tanks are stunning, and the coral selection draws serious reef keepers from across the area. Owner Dalton Leonard has assembled a team — including technicians like Kyle, Gigi, Cole, and Cullen — that customers describe less like service providers and more like trusted partners in their aquatic journeys.
Saltwater is clearly the heartbeat of this operation. Dalton's deep science knowledge has rescued neglected 125-gallon salt water tanks and transformed 240-gallon reef systems into showpieces. Customers rave about quarantined fish and a beautiful coral selection, and the store stocks invertebrates that help build thriving saltwater ecosystems.
One long-term customer reported that nine months in, their tank continues to blossom into a gorgeous reef environment — a testament to FantaSEA's commitment to lasting results, not just initial sales. What truly sets FantaSEA apart is their maintenance and installation service. Technicians visit on bi-weekly schedules with clockwork reliability, and after every service call, customers receive detailed reports complete with photos documenting exactly what was done.
Dan has rewired entire filtration systems, Gigi fine-tunes water parameters with meticulous precision, and Cullen responds to fish health emergencies the same day they're reported. One customer who had cycled through aquarium techs for 16 years called FantaSEA the first truly professional operation they'd encountered. The design and installation side is equally impressive.
FantaSEA handles everything from initial proposals and video consultations to full aquarium builds, creating custom setups that customers proudly show off to guests. Whether it's a modest home aquarium or a massive 240-gallon saltwater system with all the bells and whistles, the Crofton team delivers aquarium designs that bring genuine peace and beauty to people's homes.

Outstanding experience from beginning to end. I recently purchased a fish tank, and Dalton made the entire process exceptional. His professionalism, deep knowledge of the saltwater hobby, and genuinely friendly attitude set him apart. You can tell he truly cares about helping customers make the right choices. The facility itself is impressively clean, organized, and clearly maintained to a very high standard. It reflects the same level of care and expertise that Dalton brings to his work. I highly recommend this place to anyone in the saltwater hobby. Five stars all the way — and Dalton deserves every bit of the praise.

We look forward to continuing our aquatic journeys with FantaSEA! JAN 2026 - Continuing 9 months after our initial review, and the tank continues to grow and blossom into a beautiful salt water ecosystem. We couldn't be happier with our advice, quality of the fish and invertebrates, and the service!

Outstanding Service from Gigi at FantaSEA Aquariums! Gigi has been my tropical fish service and maintenance tech for some time now, and I couldn’t be more impressed. Since she took over, my aquariums have never looked better — the water stays crystal clear, my fish are thriving, and the entire system runs flawlessly. She’s incredibly knowledgeable, detail-oriented, and always goes above and beyond to make sure everything is perfect. Whether it’s adjusting water parameters, checking equipment, or offering advice on new additions, Gigi handles it all with professionalism and genuine care. It’s clear she takes real pride in her work, and it shows every time she visits. FantaSEA Aquariums is lucky to have someone like her on the team. Highly recommend their services — especially if you’re lucky enough to get Gigi as your tech!
