Although I did not book any services, they still gave me other recommendations and advice for my aquarium goals.

We are so happy that we’ve started using Fish Ninjas to help us with our ~85 gallon custom saltwater tank. They did an amazing job for a great price. They also gave us some useful tips for when we do cleanings. We highly recommend them.

Fish Ninjas have been out twice to my home to clean our turtle tank and they are so quick respond and both times have been out within 48 hours ! Pricing is better then anyone I have reached out too. Honest and quality work. Wont let anyone else touch the tank except them moving forward!

Was really great working with Ben. He was very knowledgeable and answered all of my questions. Made me feel at ease. I highly recommend him.

I truly can't say enough good things about Ben from Fish Ninjas! A true pro, super knowledgeable and fun to build a tank with. My new aquarium looks like it could be in the Denver Aquarium or a museum. He helped me rebuild my tank after a 2 state move and it's never been cleaner, more organized or looked better. Proceed with confidence!

Loved the job he did on my two tanks. I will definitely be having Fish Ninja back for a once a month cleaning.

Ben was awesome! Showed up on time, did an excellent job and the value was great! We are having him replace the existing tank with a new one.

Aidan with Fish Ninjas did an amazing job with cleaning my saltwater fishtank. He arrived on time, was polite and professional. He provided recommendations which I really needed and appreciate. I asked Aidan questions about my fishtank and the type of filters I have to inquire his knowledg about my particular fishtank and he did know what I was talking. Fish Ninjas will continue to maintain my saltwater fishtank from here on out.
