The Neon Blue Goby arrived quickly and looks stunning in my 10-gallon tank. The blue coloration is vibrant and has deepened nicely after a few weeks. It’s very active and helps keep the algae under control. A great addition to any freshwater setup.

I was initially skeptical about a small fish with such bright colors, but it’s actually quite charming. It’s not aggressive and blends well with my other fish. The color develops slowly, but it’s worth the wait.
