I ordered 2. When they arrived they appeared lethargic, but once added to my tank their colors brightened up and they started swinging.

Arrived alive and energetic. Is very curious and brings a lot of personality to the tank.

Arrived alive...so tiny! I was concerned that he would become food for the larger fish...today is the second day and he peeked his nose out during feeding time :) now he is swimming with a little more confidence! I hope he makes it. My aquarium is a peaceful one, but anyone can become food! Thank you!

Love this Blue Neon Goby - Captive Bred! He is so beautiful and such an interesting personality! He doesn't bother anyone and has actually become friends with our yellow wrasse! They swim attached at the hip looking for food! He is a very mellow swimmer who loves swimming through the rock work to find new caves. He is a little hard to feed when competing with quicker eaters, I let a couple pellets sink in front of him and sink a few spirulina flakes! I highly recommend him, he is sweet, beautiful, and easy!
