okay, i was considering buying one of these for my one tropical tank but i forget what they were called. they were in a tank with gobys, or maybe they were the gobys? they were white ish and about 2" long and almost looked like they walked along the bottom of the tank. they had sand as their substrate so i wasnt sure if that was necessary for them but i was just wondering if maybe anyone knows what this fish was? i know its a broad description but i cant remember anything else Lol i was shoo-ed out of the store by my family who had gotten fed up with my looking at the fish for so long Lol

Did they look worm like? With a dorsal fin?

aren't gobys marine fish?

Why yes they are fishies.

They sound like a type of dragonet or goby and they most certainly are marine fish, and unfortunately some of the hardest marine fish to keep alive. They are all wild-caught and often cant find enough food in captivity and eventually starve to death. They are so adorable, though.

Is it a Knight Goby?
