The owner, Dalton Leonard, takes care of my fish. His superior science knowledge has turned my 125 gallon salt water tank from a constant problem into one which looks great. He's reliable, personable, funny and very creative. My tank is always pretty and healthy.

Fantasy aquarium services is a game changer . I can't tell you what a friend they have become. Dalton and Cullin are wonderful. They showed up at just the right time. I'm 63 years old and have a 240 gallon saltwater tank with all the bells and whistles...well almost all. They completed that package and have made it so beautiful and enjoyable, freeing up so much time, energy and worry. Thank you all for a job well done.
