The Blue Fin Watchman Shrimpgoby (Cryptocentrus fasciatus), also known as the Y-Bar Watchman, can be found among the rocky outcroppings of southern Asia. They have a brown or tan body with light stripes along the dorsal section, as well as a vibrant blue anal fin and blue specks peppering the body. They are known to form a symbiotic relationship with shrimps to secure their burrows. The Watchman thrives in tanks with plenty of live rock, a sandy substrate, and a tightly sealed lid to prevent escapes. Only one should be kept in each aquarium unless it is in a very large tank as they can become territorial. They will feed on a varied carnivorous diet and are known to be able to spawn in home aquariums. Males and females differ slightly as the females have a more muted coloration. Overall, this is one of the best all-around fish you can have in your tank. It is easy to care for, hardy, fun to watch, beautiful, and a wonderful tank mate.
