what people are saying...
“We just received our healthy, marbled Half Moon Betta from Coast Gem USA. Excellent communication from start to finish and the quality is amazing. They are consummate professionals who I highly recommend.”
“100% the best online store I’ve ever bought from. Excellent customer service, and reply really fast. My betta and panda corys arrived perfectly fine. They replied within about 20 minutes and refunded me.”
“I ordered a Betta back in March and he shipped out fast and arrived 2 days later healthy, gorgeous and definitely the fish I ordered. I made another order for a male Betta this week, same thing.”
“I ordered an Oranda from Coast Gem USA and the whole experience was honestly perfect. The fish showed up looking great—healthy, clean, and exactly what I was hoping for. You can tell they really took their time with the packing.”
“Great place for a vast assortment of freshwater fish. I’ve bought in-person and online, both have been great experiences with my purchases. Thank you Coast Gem, you guys are awesome!”
“This place is amazing! They have a bit of everything and they have knowledgeable staff to help you with fresh water fish expertise. Caesar was very kind and professional with getting our new cichlid peacock.”
“My giant betta showed up healthy with beautiful color. Took a few weeks. I knew from the start after reading reviews that it’s a slow process and this fish having to be imported would take a little longer but well worth the wait.”
“How this place only has 3 stars is beyond me. I did have to catch my own fish. However, the quality of fish that I got (African cichlids) was amazing!!! I paid much less than had I have purchased them somewhere else.”
“I originally had a pretty good experience ordering online from them. I ordered 5 betta and they took a little longer than expected to get to me but the quality was exceptional. I was so impressed that on a trip down to San Diego I checked them out.”
“I ordered 5 orandas. At first they were a little stressed, which is normal due to the trip since I live in Florida. After I quarantined them, they settled in beautifully and I was very happy with them.”
