We are constantly updating and recently expanded our stores space to better serve our customers. We pride ourselves on our ability to obtain "rare" or "hard-to-find" species.

Customer Testimonial


"Wonderful store with dedicated staff. Ive seen the same people working there for years. They’re always available to answer questions for the novice or to be sounding boards for more intermediate advanced owners. Wonderful diverse selection. The worse thing I could say is they have so much you really have to take the time investment to look around but most assuredly what you want, is somewhere. And if it so happens it isn’t, they’ll procure it for you. Love the betta selection and even though I don’t do saltwater tanks, the exotic corals and sea life are better then a trip to most aquariums in Michigan. Great fun, reasonable prices. Once I found this place I haven’t gone to another since."
