Atlantic Mudskipper

Live crickets, mealworms, frozen bloodworms — eats out of the water on land patches

Amphibious goby that needs a paludarium: half brackish water (specific gravity 1.005–1.015), half exposed mud/sand banks under a basking lamp. Climbs onto land to feed and bask, returns to water to wet its skin. Highly territorial — keep 1 per tank unless the land area is huge.
