The very next day ALL the leafs of that specific species fell off! The other plants were fine , I then called Saturday the very next day to ask about either an exchange or a refund and I spoke to a representative named Mike whose immediate response was "no! there's something wrong with your tank" / "all sales are final" Mike offered no help or tips or nothing just simply blame my tank, which already has shrimp and fish and other vegetation that is doing just fine........ Definitely do not recommend buying from here unless you know for a fact, if something doesn't work out, you're screwed no refunds, exchanges, or any help. Bad bad business practice

Aquatic Collection is a standout shop if you're serious about reefing. Every time I've been in, the…read morestaff has been extremely helpful, friendly, and genuinely knowledgeable. They take the time to answer questions and make sure you're making the right decisions for your tank instead of just trying to sell you something. One thing that really sets them apart is the products they carry. They have items on hand that you don't typically see at other stores--for example, I was able to find a roller mat gearbox repair kit there, which is something most places don't even stock. That kind of attention to what reefers actually need goes a long way. Their coral selection is also on another level. They consistently have more unique pieces than just about anywhere else I've seen, which makes it a great place to find something different and add real character to your tank. One thing I really appreciate is that the owners are always there and involved. You can tell they genuinely care about the store, the livestock, and making sure customers have a good experience. Overall, it's a very well-run store with a strong mix of knowledge, customer service, and unique inventory. Definitely a go-to spot if you're looking for both hard-to-find equipment and standout corals.

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

This review is describing my experience with everything pet bird related at this store: cage, food,…read moretoy selection; cleanliness and organization; and the worst part--that they sell birds. Not only do they sell birds, but they house the birds in a tiny, cramped, windowless room in tiny cages, with one fluorescent ceiling light and what appears to be no human interaction or fresh air or appropriate light. The room is about the size of my bedroom, and there are cages stacked to the ceiling full of birds, but the cages are tiny. Back when I didn't know any better in the '90s, I purchased two parrots from pet stores, as "hand-raised babies," but those stores had all the birds in appropriately sized cages with sunlight and lots of toys and out time with visitors if you sanitized your hands. They felt out the potential owners and didn't sell birds to just anyone. Now I know better, as I volunteer with a local parrot rescue that has to turn away hundreds of unwanted pet birds a year on top of the hundreds they take in. One of those volunteer duties is doing home visits for the adoption applicants, and one took me this week to near this store, and the applicant told me about it and showed me this terrible-looking seed mix they purchased there for pets. So I stopped by this store to see what/why they were selling, and the sad and crowded windowless bird-commodity room made me cry. I left in tears. I had first browsed the shelves for toys and food, and I found the shelves unorganized, out of stock on several items, and the floors dirty. Plus a cat running around. And the cages they were selling were all tiny as well. Here's something significant and equally emotional. Under "pets" on the front page of their website, they strongly encourage adopting from shelters for dogs and cats. SO WHY NOT BIRDS? Birds live longer, are more complicated, are often more intelligent and with more complex needs, and our rescues are overrun! WHY?!?! (Profit! And it's terrible.) This is their own words--why don't they believe this for birds??!! They should contact every rescue on the West Coast and find out how overrun we are. "We have in stock a selection of small pets which include birds, fish, rodents, reptiles, amphibians, and arachnids. If you are looking for a pet kitty or pooch, we HIGHLY urge you to check out the local shelter where there are great animals looking for loving homes. Mike's Feed & Pets does not sell dogs or cats but we do have a complete line of products to help you care for them"

The reply back was, "Yes, we have in stock." So the next day I drive all the way from the Central Valley to check out their Shubunkin stock. To my dismay, I'm told by an older man at the back store that they don't have any Shubunkin goldfish. I told him that I emailed Hank and he said you had them. The man then tried to sell us on Koi, but we told him we specifically need Shubunkin since we have many plants in our pond and the Koi would eat them, that's why we specifically are looking for Shubunkin goldfish. He then directed us to some Comet goldfish but not what we were looking for. Tried to look at the plants and other fish but the thought of me being lied to and driving that distance from the Central Valley was too much, so we left. This company was deceitful just to lure us into their facility. If they could lie about a simple straight forward question what other things would they lie about just to get you to buy something. Would not go back again! Will be searching for a trustworthy Shubunkin goldfish dealer elsewhere. What a way to deceive a potential customer.

So, I had to cover my nose and ran to the other side of the shop right away.

I've purchased dog food for my pups many times at this location and never had a complaint/problem. Today will be my first mainly to warn customers of ***EXPIRED dog food. I'm not a stickler on expiration dates but selling bags 3-4 month (May 2025) passed is ridiculous/wrong! I usually buy a supply 2.5 weeks ahead of time if I know I'm running low. When I finally opened the bag a few days ago the food was obviously RANCID! Dogs will usually get excited in anticipation of their food...they got a whiff and walked away...it was very evident! Partly my fault for not checking but I would hope a store wouldn't sell OLD food. This is the first time it's happened but the interaction I had with the cashier wasn't pleasant. Flat out rude! "You have your receipt? It's open and we can't resell". Valid question but tone of this worker was very condescending! I get they want proof you bought from them but who keeps their receipt each time they buy their pets food...I guess I will now as bags must be unopened to return...um, how would I know it's BAD?!!! I mentioned "can I speak to Laura, the Manager as I was told (previous visit) I would need a receipt BUT there are exceptions and to ask". I even asked "can you work with the manufacturer?"....ignored. All I wanted was a replacement for: ****** $42 for a bag of 12lbs of Natural Balance I purchased....same item! In any case...I'll write the company and hope to get a voucher for a replacement and a better outcome. #annoyed

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.

I have worked with a few folks who have been good, but I wanted to get my pond to the next level. Elan IS next level. Not only is he helpful, honest, hardworking, and genuinely a nice guy - he is also open to teaching you how to be a better pond and koi owner. I've been working with Elan for about 2 years now - and have nothing but great things to say. He has helped me improve my pond - get better at testing it - and keeping my fish healthy and happy! Beyond this - he has helped with getting new fish when we had one pass away. Elan and his team are the best and I cannot recommend them highly enough.

Elan saved our pond--and our koi!**…read more When we moved into our new home, the backyard koi pond was in terrible shape: murky, greenish water where we could barely see the fish. Thankfully, we found Elan online. He gave us a quote over the phone and clearly explained how he would clean and restore the pond. When Elan arrived, he gently captured the koi and smaller fish, placing them safely into buckets. He then drained the filthy water completely. What he uncovered was shocking--decades' worth of mud-like waste from fish droppings and uneaten food, likely accumulated over 70 years. Wearing a scuba suit, Elan meticulously vacuumed and scooped out the muck, then pressure-washed away layers of algae. He didn't stop there--he thoughtfully rearranged the decorative bricks and stones and carefully tied down the aquatic plants for a neat, natural look. Finally, he refilled the pond with fresh, conditioned water and gently released the fish back into their beautifully restored home. We were absolutely amazed--the transformation was stunning. Now we truly enjoy watching our fish swim happily in their crystal-clear pond. We can't thank Elan enough for his expertise, dedication, and genuine passion for aquatic life.
