STOP, DON'T waste time looking for other aquarium services. You found the BEST one, I promise…read more Since this review will be long, thought I would emphasize on the point of my review from the beginning... instead of making you read through everything. Many businesses will help you buy a new tank... but have you ever tried to get rid of one? Not just any old fish tank but a giant one, where you could probably teach your kid to swim in it... We are talking about 400-gallon fish tank that was built way too DIY, extremely heavy, filled with livestock, ton of sand and rocks. If you are not into fish, this is easily 4,000 lbs... with many surprise attacks from the DIY "Offense Team". You really want someone who knows what they are doing... unless you want a mini flood of saltwater in your living room.. I contacted MANY businesses including junk removal but wasn't satisfied due to poor communications, lack of planning/professionalism. Thankfully, I read about Ocean Treasures Servicing on social media and did my research/stalking via FB, IG, and... reef forums and found only great things. The owner himself, Daniel, came down all the way from SF for a in person consultation then emailed me a meticulous thought-out plan on step by step of removing the giant tank. The Game Day - Daniel came with 3 team members + 1 cargo van + 1 U-Haul (this thing was huge..) Everyone from the team treated the house like their own, laid out floor protectant all over, swept every bit of sand before attempting to move any heavy items (a little sand that gets dragged can make quiet an impression on your floor), safely caught all the living creatures (all alive :D), and finished the job as if they literally CTRL+X the whole thing out of the house. Ocean Treasures Servicing is simply AMAZING. You would think after all the trouble of getting rid of a tank, I would be done... but NOPE! Since I found the best team I can trust, I am in the process of building a replacement one that is professional made by Daniel and his team...... No more DIY, unleveled, loud sounds, and random cuts from DIY stuff.... Don't Do it yourself, it's not worth it.. Trust Daniel and Ocean Treasures Servicing and just enjoy the hobby.

Our aquariums are clear and clean and he was even able to remove some of the existing surface scratches in the plexiglass! A bonus I hadn't anticipated. Dean created the optimal breeding environment in our tanks. Our angel fish are happily laying eggs (although they are still learning how to protect them) and our live bearers are steadily reproducing. My mom spends several hours a day enjoying the action in her aquariums; watching her tetras dart in and out of the lush plant life and her plecos play hide and seek in the drift wood. Her aquariums have never looked better and she has never spent so much time enjoying the view of the underwater sanctuary Dean helped us create. Thanks Dean! You rock!

I gave them a key to my house so they could come by every three weeks to maintain my aquarium, which requires a lot of trust, and they handled everything professionally and responsibly. Not only did they take excellent care of my fish, but they actually made the aquarium look better than it ever had before. The water quality, the setup, and the overall appearance were noticeably improved each time. When I returned home, all of my fish were healthy, active, and clearly well cared for. It gave me real peace of mind knowing my aquarium was in such good hands while I was away. I highly recommend ABC Aquatic to anyone looking for reliable, knowledgeable, and trustworthy aquarium maintenance. Outstanding service from start to finish.

Not the cleanest aquarium store I've been to but at least I didn't see many dead animals. The shop was dimly lit in some areas so I'm assuming that they're in the middle of re-organizing or something. Livestock price wise, i think it's reasonable. Although some tissue cultured were on the pricier side. The selection of plants and livestock were OK, I would probably only visit if you need equipment though. They have some ADA, UNS, Chihiros, CO2 tanks, etc. Here are some of the livestock prices to give you a sense of what they charge. This is not a comprehensive list but rather some livestock I was personally interested with: Prices as of June 2026: FW Fish Assorted Male Bettas - $10 Ember Tetra - $5 False Bandit Cory - $12 Kuhli Loach - $6 Longfin Bronze Cory - $10 Pea Puffers - $8 Pygmy Corydora - $6 Sterbai Cory - $15 Super Red Bristlenose - $30 Whiptail Catfish - $20 SHRIMP Amano Shrimp - $7 Bamboo Shrimp - $10 Black Tiger Shrimp - $15 Cherry Shrimp - $8 Opae Ula Shrimp - $5 Super Tiger Shrimp - $15 SNAILS Jade Mystery Snail - $5 Japanese Trapdoor Snail - $9
