Copper Awesome

Great fish store. Set up well, awesome fresh and salt water inventory at great pricing. Ceasars no more for me. Much better than we have had in the past. I recommend them to everyone. Check them out if you are a fish lover!

Great place and a great staff. They give you quality fish without the high mark up in pricing. Bought my Piraíba Catfish from them and couldn’t be happier. Rarely see them for sale, or for $275+, but they had one $89.99!

B.O.B's Black Bass Beasts

This place is by far the best place in Sonoma County. You will not be disappointed with how you are treated and you will not be taken advantage of our up-sold. They are honest and fair. I highly recommend and I hope people go and do business here.

It’s nice to have a new tropical and salt water aquarium place to go. Good customer service and a nice selection. Prices are good and all the fish I got are still alive and doing well. They can also order anything for ya so that nice! I recommend!

I visited here with my my Pops and the staff was very nice, the store was really sharp and organized well, and the options plentiful. I saw a great selection of fresh/saltwater fish, corals, and even some sharks! I will be back soon!
