About
I am a fairly new and up and coming professional in aquarium keeping. However, I have a unique background of having studied environmental sciences in my undergraduate.
I am willing to learn and try new ways to improve fish keeping. I have been on a five-year journey of learning the ways of the fish. Wednesdays and Saturdays I do video consultations through Zoom.
Due to the rising cost of living, my rates are climbing for 2026-2027!
I can do a free video consultation or free cleaning to get us started.
Thank you!
David

David came out to my home to service my 180 gallon cylinder aquarium that houses 7 large discus fishes and small school of cardinal tetras. And after keeping many aquariums from saltwater to fresh water over the last 40+ years I found him to be very knowlegable and very hands on Professional. He also shared some great tips with me about keeping my fishes healthy. And I look forward to using his services for years to come!

I've had my fish tank for 13 years. have had problems before but my tank completely crashed. David came out, discussed recent changes i had done, and determined what happened. He cleaned the tank and tended to the problem. He knows this business and understands problems and solutions. I will be working with him periodically to ensure this doesn't happen again.

David was a competent worker. He cleaned our 65 gal tank, being careful of its inhabitants. He changed 50% of water, vacuumed gravel, cleaned glass faces and tops, along with the plastic plants and broke down the canister filter and cleaned it. He provided extra carbon ( I was short on amount) and provided two carbon bags for the filter. He even noticed my catfish had borne babies! We would recommend David for your aquarium needs such as servicing and maintenance.

David arrived early and was very knowledgeable. He did a great job and it was less expensive than expected. Even though we have a small aquarium he took the time to answer all our questions and make a plan for us to follow to keep it clean and healthy between his check ups. Highly recommend!

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
I'm traveling long distances for my customers so I am changing my fee structure. It has been challenging to make it work financially when I travel great distances and receive little compensation for my time and work. Now I am charging for travel time to and from the location in addition to my work at the location.
My current rate isper hour including
What is your typical process for working with a new customer?
I like to give them freedom to share their ideas and to work together on projects. I know that we are all still learning how to get this aquarium thing right.
What education and/or training do you have that relates to your work?
I do have a Bachelor of Arts degree in Environmental Sciences.
And I worked part time under an aquarist who had 15 years of experience under his belt. I trained under him for two years for a few days a week.
And most recently, I've learned from handling more and more different types of aquariums. Now I've worked on hundreds of tanks and have been perfecting my skills and knowledge through my good and bad experiences.
