Common questions
Asked at the counter.
Is Sea Cave a public aquarium or a fish store?
Sea Cave is Erie's retail aquarium store — a sales floor of live saltwater and freshwater display tanks you can walk through, with fish, coral, plants, and equipment all for sale. There's no admission; just stop in at 660 East 14th Street and browse the tanks.
What are Sea Cave's hours and where are you located?
Sea Cave Inc. is at 660 East 14th Street, Erie, PA 16503, open Monday through Friday 12:00–6:00 PM and Saturday 11:00 AM–4:00 PM, closed Sunday. Call (814) 456-9445 before driving in if you're coming from out of town — livestock rotates daily.
Do you sell both saltwater and freshwater fish?
Yes — Sea Cave stocks both saltwater and freshwater livestock under one roof, including community freshwater fish, reef-safe saltwater fish, captive-bred coral, invertebrates, and live plants. Most tanks are visible from the sales floor so you can see exactly what you're buying before you commit.
Where can I buy live coral near Erie, PA?
Sea Cave Inc. at 660 East 14th Street in Erie carries captive-bred coral frags and colonies, plus does in-house propagation so the stock rotates weekly. Buying local means no overnight shipping shock and you can inspect polyp extension and coloration in person before bringing a frag home.
How much does saltwater aquarium maintenance cost?
Professional saltwater service is priced industry-wide at roughly $1.25 per gallon per month with a $150 minimum, usually visited weekly or bi-weekly depending on livestock bioload. Sea Cave quotes per tank — call (814) 456-9445 with your tank size and we'll price it; most homeowner tanks land between $150–$400 per month.
Can I get a custom-size aquarium through Sea Cave?
Yes. We don't build tanks in the shop — custom-size aquariums are built by the manufacturer and shipped direct to you. We help you spec it and handle the rest: stand, filtration, lighting, rockscape, and a stocking plan. Stop by 660 East 14th Street or call (814) 456-9445 with your dimensions and what you want to keep.
