Fitz's Fish Ponds in Colts Neck, New Jersey has built a national reputation as one of the premier koi pond builders and maintenance providers in the country — and the reviews make a convincing case. Founded by Brian Fitz, this isn't your typical fish store. It's a full-service operation that designs, constructs, and maintains koi ponds of every scale, from backyard water features to sprawling multi-system builds that run under bridges and alongside home foundations.
The construction stories alone are remarkable. One Virginia homeowner recounts how Brian drove down from New Jersey with a crew to tackle a complex koi pond that local builders were afraid to touch — a system running alongside the house foundation, under two bridges, and feeding into natural streams behind the property. The crew, led by Jimmy and Mike, coordinated repeated trips to sync pond construction with the home build itself.
That level of commitment defines Fitz's approach. On the maintenance side, the names Brett, Abraham, and Eric appear again and again in glowing reviews. These teams handle seasonal pond cleanouts, string algae removal, netting installation, filter diagnostics, and emergency repairs.
One customer describes how, after an electrical fire destroyed their filter system, Fitz's dispatched Travis immediately to set up a temporary solution to protect the fish before sending a full construction crew to rebuild. That kind of rapid, compassionate response earns fierce loyalty. Fitz's also operates a thriving online store shipping exotic koi nationwide.
Kyle, the staff member most frequently mentioned in fish-buying reviews, personally assists customers from Tennessee, Virginia, and San Diego in selecting individual koi via phone or video, patiently showing options until each buyer finds the right fish. Jan is another standout for in-person guidance. The selection of exotic koi and pond plants anchors the retail side, but the real draw is the expertise.
Whether it's a 500-gallon cleanout, a leaking filter connection, or an ambitious multi-stream build from scratch, Fitz's Fish Ponds delivers with professionalism that customers describe as unmatched.

Excellent customer service. I only purchased a singular moss ball, but the great care taken to ensure my little order would ship safely blew me away. Thank you Chris & Jennifer!

I live in Virginia and was introduced to the owner of Fitz's Fish Ponds, Brian Fitz approximately 2 years ago. My wife and I had started construction of our home which involved an extensive koi pond in the front of the house and ran under a bridge to the front door and under a bridge separating the master wing from the main house and gathered in the back of the house. I went to local koi pond builders who were all scared to do the job because it ran up next to the house and foundation. Brian drove down from New Jersey with a crew and saw my wife's and my vision and assured us that they could do the job. We expanded the job to include two streams that ran down to a natural pond behind the house and a completely separate system. Not only have they completed both systems impeccably, they have wowed all of the local koi pond builders and other home professionals that come to the house.They far exceeded my expectations. Jimmy and Mike were involved directly with the construction of the two systems and made repeated trips back to our house to complete different segments of the two systems to coincide with the building of the house itself. The construction of the koi pond and the construction of the house needed to happen somewhat in tandem so that neither was being done too far in advance of the other. They made sure that everything stayed on schedule and have gone above and beyond anything that one could ask. Honestly, and in large part because of Jimmy and Mike, and certainly Brian, I believe Fitz's Fish Ponds to be the best koi pond and natural stream builders in the country. I can't emphasize enough my sincerity in saying that. If you are considering a koi pond, large or small, you owe it to yourself to at least talk to Fitz's Fish Ponds. Best of luck with your koi pond construction!

Our koi pond suffered an electrical fire destroying our filter system. Hope immediatly dispatched Travis to assess the damage and most importatly set up a tempoary solution to safeguard our fish. Shortly after, the construction team led by Rudy with Julio, Axel and Jose came to rebuild my space. From the first paniced call to Beth's completion follow-up call, the entire team at Fitz's was wonderful. We were treated compaassionatly and informed at each step. Each team member was through, knowledgeable and supportive. My magnificent koi are now back at home! Thank you all for a job very well done!
