- "I caught a freshwater goby! You fresh, goby!"
An information board in the aquarium will provide information about this fish.
"These short and stocky river-dwelling fish have a lot of slender teeth for tearing apart other fish. Freshwater gobies dig holes under rocks in riverbeds to make nests for eggs, which the males guard. Other fish breeds take advantage of this protective quality and often lay eggs in goby nests."
