Carl Sharp –
The fish arrived healthy and stayed active in my 10-gallon tank. The deep blue color is striking, especially after a few weeks. It doesn’t eat much and coexists well with my cherry shrimp and neon tetras. Easy to maintain and a great addition to a small community tank.
Keith Terry –
I was worried about compatibility with my shrimp, but the goby seems to be very gentle. It spends most of its time near the substrate, feeding on algae. The color is beautiful and it looks happy in the tank.
Sam Smith –
Perfect for a small aquarium. The fish is active, peaceful, and doesn’t stress other tank mates. I’ve had it for three months and it’s still vibrant and healthy. A great choice for beginners.
