Need Supplies Too?

General Stock ≠ WYSIWYG: Species listed here represent our typical inventory. Color, size, and availability may vary. Photos are representative—not the exact animal you will receive.

Online vs. In-Store Inventory: Our online inventory is different from what’s available in-store and ships nationwide. If you don’t see what you're looking for, give us a call at 773-295-5175 and we’ll be happy to check our in-store availability.

Shipping Information: General stock items are shipped directly by a trusted third-party vendor. For local availability, visit us at 6816 W. North Ave, Chicago, IL 60707.

We proudly serve fishkeepers from Skokie, Oak Park, Elmwood Park, Forest Park, Morton Grove, and beyond, with in-store shopping and local pickup available.
