We are proud to have opened our doors in June 2017 in Frederick, boasting exclusive saltwater livestock and supplies, specialized expertise virtually unheard of in the area, and the backing of other authorities in the aquarium-keeping industry.        

Paul Mangus, the owner of Fintastic Aquariums of Frederick, became involved in saltwater aquariums as a hobbyist, over 20 years ago. He understands the passion of hobbyists and the need to serve the Frederick area. “Even after 20 years of experience, I still get excited when I see aquariums while traveling,” he says. “I know how intimidating it can be for new hobbyists just getting into aquarium keeping, so I try to make it as easy as possible for them. Through my experience I have seen just about every kind of setup there is and can help trouble-shoot some of the most challenging issues that may come up”. Paul is extremely enthusiastic about the opening of this new store. He says, “I’m ready to showcase what we have to offer and give our customers the most affordable and best quality livestock that they’ll find anywhere. We plan to be the favorite saltwater aquarium store in the DC metro area.”       
Fintastic Aquariums of Frederick joins Fintastic Aquariums of Jensen Beach (Florida) and Fintastic Aquariums of Wake County (North Carolina) in providing exceptional value and specialized knowledge of the industry. While each store has its own look and feel, customers will benefit from the combined experience of the entire Fintastic team. With a marine biologist on staff hand-selecting livestock, customers will receive the healthiest species available. Due to the high volume of all three stores, prices will be much lower than any other shops in the area.
