About
FantaSEA Aquariums sits in Crofton, MD, and the moment you walk in it's clear this is no ordinary fish store but a saltwater aquarium store built around reefkeeping done right. Owner Dalton Leonard and his crew — Kyle, Gigi, Cole, Cullen, Dan, and Alex among them — have a reputation for patience that surfaces in review after review. One first-timer admitted to stopping in every weekend for a month, asking question after question without any water in his tank yet, and still felt completely welcome.
Another customer arrived with stocking and compatibility questions and left calling the show tanks stunning and the corals and fish the pinnacle of health. The space itself is spotless and uncluttered — none of the random clutter you find at other shops, just clean, well-kept display tanks that give visitors confidence in the livestock. What truly sets the store apart is a strict 30-day quarantine on both fish and corals before anything is sold, so the saltwater fish and corals for sale in Crofton, MD have already been watched and cared for.
The coral selection is the talk of local reefers — a large, vibrant variety, from torch corals to quarantined fish, invertebrates, and dry goods all under one roof. One reviewer with twenty years in the hobby called it his favorite shop in the area. Beyond livestock, FantaSEA runs a full aquarium design, installation, and maintenance operation.
Customers describe bi-weekly service that runs like clockwork, detailed reports with photos after every visit, and techs who rewire filtration, fine-tune water parameters, and respond fast when a fish falls ill. After big-box advice left one family battling green algae, a UV light from the shop cleared it up within days. Whether it's a quick coral run or a 240-gallon reef build, the Crofton team treats every tank like its own.
For anyone searching for saltwater fish and corals near me, FantaSEA is well worth the drive.

Customer reviews
“Absolutely impeccable customer service. Dalton was very friendly and patient with my stocking and compatibility questions. Show tanks are stunning, and their stock of corals and fish are the pinnacle of health. Their staff clearly care about educating and supporting their clients. We will be back for all of our saltwater needs and when we are ready for corals!”
— Lyndsey Basham5.0a week ago“Awesome crew working there, super clean and organized store not congested with random stuff like other LFS I've been to. Everyone is super knowledgeable and prices are great! They've put up with me coming in every weekend for about a month asking question after question and not even having water in the tank yet. 10/10 can't recommend enough”
— David Yohe5.0a week ago“The team at FantaSEA are great people. Always helpful and we have been to his store a few times now. The tanks are always clean and if you love coral, he has the most well stocked and maintained tanks in the area. There are also quarantined fish and dry goods. He is always willing to help or talk over tank issues. So happy to have a great LFS in the area! Photos are for reference as the inventory changes.”
— K R5.03 weeks ago“Had an excellent experience with this company and I highly recommend them. PetSmart had given me horrible advice on how to manage my son’s fish tank. The tank ended up dirty with green algae everywhere. I decided to try out FantaSEA and they went out of their way to advise me on how take care of my fish tank. I bought a UV light from them and it fixed my green algae problem within days. I will only go to this company for future aquarium needs and highly recommend everyone else do the same. Great customer service and real expertise that you won’t find anywhere else.”
— Sameer Siddiqui5.0a month ago“We visited FantaSEA Aquariums today, and it was absolutely worth the 1.5-hour drive. From the moment we walked in, we were blown away by how clean the entire store was. Every tank looked spotless, well-maintained, and healthy, which immediately gave us confidence in the livestock. One of the biggest things that stood out to us was their commitment to doing a 30-day quarantine on both fish and corals before they are sold. That kind of care and responsibility is huge, especially in this hobby, and it really shows in the quality of their animals. Their coral selection was incredible — a large variety of beautiful, healthy, vibrant pieces that were clearly well cared for. The staff was just as impressive as the store itself. They were extremely knowledgeable, patient, and genuinely helpful. They took the time to ask about our tank, what we already have, and what would be appropriate for our system instead of just trying to sell us something. That level of honesty and care means a lot. This was easily the best aquarium store experiences we’ve had, and we go to a lot of stores. We will absolutely be making FantaSEA Aquariums a monthly field trip to check out their stock and continue supporting them. Highly recommended!”
— Ken Pollard5.0a month ago“Awesome experience first time even walking into the store. It was such a great experience went back a second day to purchase torch. Btw my wife loved it also.”
— Quan Hardy5.0a month ago“After about 12 months of trying to setup a saltwater reef tank we contacted FantaSEA and scheduled their maintenance service. While we mostly work with Alex who has our tank looking better than ever, everyone we've been in contact with at FantaSEA has been professional and knowledgeable. What a difference in just a few months!”
— Ada Sell5.0a month ago“Amazing shop and staff. Very helpful and knowledgeable about the hobby. Love this place!!!!”
— Rodney Hall4.02 months ago“Very nice local store with high quality products, coral, and fish. Would definitely recommend visiting and purchasing from here. Looking forward to returning. The display tanks are a pleasure to look at as well.”
— Mike T5.03 months ago“The best place for fish and corals, but even more than that for service! Dalton and his team just get it. They make a real effort to make you successful. I am basing my experience off of months of visits and interactions and I have been reefkeeping for 20 years and this is my favorite place. The store is beautiful and nothing like your typical fish store and the staff is knowledgeable and helpful. This is worth your time to check it out!”
