These 7 Prettiest Fish for Freshwater Aquariums Will Catch Your Fancy

Kuhli Loach

Resembling an eel, the elongated shape of the Kuhli Loach adds a different dimension to the commonly shaped fish in your aquarium. You can only enjoy looking at it at night because it is a nocturnal dweller. It loves the sandy bottom and hides under stones and inside caves. If you plan to care for this fish, it is strongly suggested that you give it a hiding area. They eat food that fall to the bottom.
