Five stars! I can’t say enough good things about this company. Billy & the whole team helped design, install, and maintain a beautiful 250-gallon Red Sea reef tank at my store—and the results are awesome. The level of knowledge, attention to detail, and custom work they provided was beyond impressive. Customers constantly compliment the tank, and I owe it all to their expertise. Truly an amazing team—highly recommend to anyone serious about keeping a show-quality reef tank

I can’t say enough great things about FishGuys! Billy & his father rose to the challenge when the new film we’re shooting in NJ called for a last minute fish tank in our setting! They did a wonderful job & provided the quickest service & all to perfection! Hey.. if you’re in Jersey.. call these guys.. I’m telling my friends in the film business that these guys belong in your source book. They belong in yours too! They're the reel deal!!

FishGuys came to our rescue after our previous tank service company left us stranded in 2021. Our aging saltwater reef tank was failing, and they not only serviced it temporarily but also expertly replaced it with a new Red Sea tank. Bill Jr. and his father Bill Sr. provide exceptional service, showcasing an impressive attention to detail and a vast knowledge of corals and fish. We've transitioned from being hands-on service people to delighted spectators, thanks to their expertise. Our fish tank room has become a relaxing oasis, allowing us to unwind without any worries, all thanks to the highly responsive and skilled FishGuys, true masters of their craft.

Billy and his father Bill are the best Fish Guys in New Jersey. They took over the Maitenence of our reef tank as well as 2 other tanks and they have never looked better. Beautiful corral and fish, not 1 thing has died. We get endless compliments on our tanks and they look beautiful. I highly recommend Fish Guys llc!!!
