About
Fitz's Fish Ponds sits in Colts Neck, NJ, and has earned a reputation as one of the most respected koi and pond specialists in the region — a fish store where the counter staff genuinely know their craft and the crews who service ponds across New Jersey get named, by hand, in review after review. Walk in and you are likely to be greeted by Jan, Gil Anaya, or another team member who treats first-time pond owners with real patience. Bill, building his very first pond, credited Jan Mizak with walking him through every product and recommendation until he felt confident; Brenda stopped in for guidance on a DIY bog filter project and left with the know-how to pull it off.
Gil regularly helps customers pick out the right supplies and recently pointed a buyer toward a Father's Day discount on a fish purchase. That hands-on, in-person guidance is the heart of the place. The retail floor anchors on exotic koi for sale in Colts Neck, NJ, alongside pond plants, moss balls, filters, pumps, and the everyday supplies that keep a backyard water feature healthy.
Longtime customers call it their go-to spot for koi near me, praising both the selection and a staff that treats them like family. Beyond the shop, Fitz's runs full-scale pond construction and seasonal maintenance. The cleanout crews — Marshall and Mauricio, Justin and Zach, Abraham and Spencer, and Felix among them — handle spring cleanups, total drain-and-cleanouts, string algae removal, netting, and careful fish relocation into holding tanks before returning the koi home.
The construction team, including Mike, Josh, and Jimmy, diagnoses weak waterfall flow, repairs and replaces filter pumps, and builds koi ponds from the ground up. Founder Brian Fitz still drives the most ambitious custom builds. From a single moss ball to a pump replacement to a complete koi pond, Fitz's Fish Ponds brings the kind of professional, caring work that turns first-time visitors into customers for life.

Jan Mizak was extremely knowledgeable, patient, and incredibly helpful throughout the entire process. He took the time to answer all of my questions, explain the products, and make recommendations that gave me confidence moving forward with the project. As a beginner, having someone willing to share their expertise and guide me step-by-step made all the difference. Thanks to Jan’s outstanding customer service, I’m excited to continue building my pond and look forward to doing all of my pond business with FITZ’S FISH PONDS in the future. Highly recommend! Bill”
