Description
Engineer gobies, also known as convict gobies or worm gobies, are a unique and fascinating species native to the Indo-Pacific region. They are known for their burrowing behavior, constructing intricate tunnel systems in sandy substrates, which they use for shelter and to raise their young. These fish exhibit interesting color changes as they mature, initially displaying black and white horizontal stripes, which later transition into vertical bands.
