They'll let you browse & trust me, you'll need time to check out all the tanks. They are always busy--cleaning tanks, feeding fish, helping customers, stocking the floor, never have I seen anyone just standing around. I have been to multiple other local fish stores in my couple of years of fishkeeping experience, and some are gross and dirty, some are just ok, and some are downright sad. So I'm happy to drive all the way here to be guaranteed a clean, welcoming environment. (I will always choose a family owned shop if there is one, and you should too!) The fish & plants they have in stock change constantly (follow their Tik Tok to see the latest arrivals). They are always super helpful in choosing which fish & how many to get, which can be in a tank together & which ones shouldn't. They helped me pick out a whole new tank & all the accessories I'd need based on the kinds of fish & style of tank I was looking to set up. Their aquascaping table with measurements on it is super helpful to get an idea of tank layout for your rocks & wood pieces. Their example tanks (sand waterfall & a beautiful planted community tank) are fun to look at for ideas. I have been back multiple times now, for both advice & purchases. I have also called with questions & every single time, they have been great. They actually answer on social media too. I highly recommend them & honestly will always be stocking my tanks here moving forward. I guess I'm a "regular" now too, lol. 10/10!

Several reviewers have shared similar experiences, and posts in other Facebook groups have accused them of increasing prices only to offer a 50% discount to reach the original price. Although they appear to be kind and willing to assist, I awarded them three stars.

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.

He does informative events at the shop and I will definitely keep my eye out for the next one. The director of the Cal Academy has done one where he discussed the giant aquarium and how it was built. Sounds really cool! This shop has sea horses and garden eels! It's a great place to go for aquatic needs and also for the events Kenny hosts.
