  • Quick alive and healthy
Fish arrived earlier than the shipping estimate. All were alive and healthy looking. Hornwort looks vibrant. Overall very pleased with this seller.

  • DISAPPOINTING
A small cardboard package arrived with no label saying the contents were alive and the only insulation was bubble wrap. Opening the small water-filled plastic bag was difficult and I only counted 5-7 fish, one floater and no plant as advertised. After transplanting to our outdoor pond, they disappeared and I have not seen any since. The pond still has mosquito larvae so this was a waste of money. ... show more

  • Cool Little Mosquito Fish
I ordered 20 live mosquito fish on May 25th and received them on June 2nd. I consider that fast shipping for someone not on Prime. (5 stars) Packaging was solid and a lot of effort was placed in the packaging. The fish were surrounded by ridged Styrofoam and what looks like a cooler pack. Tiny pellets of food were also included. (5 stars for packaging effort) The fish were double bagged with a small cutting of hornwort plant and this is where Quinn's Fins made a little mistake. These fish are so tiny and they like to swim to the corners of the bag, then get trapped when the package moves during shipping and die. (4 stars for not thinking about this issue with tiny fish) Suggestion for future shipments: You already tie a rubber band to seal the bag, tie a rubber band on the bottom of the bag so there are no corners for the tiny fish to get trapped. Quinn's Fins probably assumes there will be shipping casualties and sent 23 fish. 7 fish dead on arrival and 16 fish made it alive. I placed the 16 fish into a 10 gallon tub with pond plants and mosquito larva loaded in the tub. These fish "hunt". They sneak up on the larvae and when they get close enough, it's gone in one gulp. No larva to be found in 24 hours and they just had babies on June 8th! (5+ stars for the coolness factor) My final score is 4.95 stars (not allowed) so I have to take off one star for the plastic bag corners. I will order these again next year. Not looking for a refund because I will quickly have way more than 20 fish in a month. ... show more

  • Only received 15 of 20 fish and no hornwort included
All fish came in alive and healthy. Although, I only received 15 fish instead of 20; and like many others there was no hornwort included. Also, even though the fish were all alive I was a bit disappointed with how they were packaged. The bag of fish itself was well wrapped with bubble wrap, but the bag was leaking a bit. Also, the box was quite a bit bigger than the bag with no packing paper to minimize jostling. Lastly, there was no “live fish” etc sticker on the box to ensure it was handled with care. ... show more
