Chicago’s Go-To for Custom Aquariums & Maintenance
We’ve spent 25 years in this industry, and we’ve seen it all—from downtown penthouse reefs to backyard freshwater setups. We didn't start Big Fish to be another faceless corporate service. We’re a local small business that believes in doing things the right way the first time. Whether we’re designing your dream tank or coming by for a regular cleaning, you’re getting "big-league" precision with a local Chicago handshake. No scripts, no nonsense—just a thriving tank and a team that actually knows your name.
aquarium maintenance & design
"We handle the dirty work so you can enjoy the view."
Look, we know your time is tight. You want a clean tank without the headache. We’ve been maintaining accounts across Chicagoland for over two decades. Whether it’s an algae bloom that’s gotten out of hand or you’re finally ready to build that custom reef, we treat your setup like it’s sitting in our own living room.
Expert Water Testing & Consultation
"Stop guessing and start measuring."
We come from a background where precision is everything. Most shops will give you a cheap paper strip test that doesn't tell you anything. We don’t play that. We use professional-grade digital gear to find exactly what’s off in your chemistry—Alkalinity, Calcium, Phosphates, the works. We give you the data so your fish stay alive and your corals actually grow.
Vacation Feedings & Checkups
"Go on vacation. We’ve got your back."
Don’t leave your tank in the hands of a neighbor who doesn’t know a protein skimmer from a heater. Our team checks your systems and feeds your fish like they’re our own. You get a text, a peace-of-mind update, and a healthy tank when you get home.
