There are not too many fish that possess horns. The two that most readily come to mind both live in saltwater; the Cowfish and the Unicorn Fish. However, the Rhino Garra is a horned fish living in freshwater and is perfect for specific aquariums.
The horns of this bizarre fish appear most prominently on the males of the species which can be further distinguished from the short-horned females by having white pimples (tubercules) all over their face.
These horns are not sharp, and the fish will not charge you like a bull while you are doing tank maintenance. Instead, they are fleshy and can be held erect when the fish is feeling aggressive or preparing to fight a rival male.
Tank Setup and Fish Keeping
Like other species of Garra, they do not like the presence of other bottom dwellers or fish with similar body shape. This is especially true of a fish that has been kept singly for any length of time.
If you are going to hold more than one though, you’ll need a relatively large tank and save no less than 4. A single Rhino Garra can be kept comfortably in a 30 gallon/ 110-liter tank. They also tend to demonstrate food aggression, so keep them with fish that can avoid their jealousy based attacks and will not feel bullied such as hardy barbs and danios. They do best in a hillstream style setup but can be kept in deeper tanks with sufficient flow, heavy aeration, and clean water.
12-15cm/ 5-6 inches
Although rhino Garra grazes on algae and biofilm, they have not dedicated algae eaters. Instead, they happily take prepared foods, sinking pellets and bloodworms. They will also eat algae wafers.
They thrive in a hillstream tank with variously sized stones. The substrate should be gravel. The container must be over-filtered to ensure it is free from organic deposits. Use multiple powerheads and aerators to provide current and add extra oxygen and surface movement to the water. Cover the tank-Garra can jump!
Egg-scatterers. Reproduction has been accomplished using two males per female. Spawning is triggered by mimicking the monsoon season. After conditioning them on good food in swiftly running water, turn off the powerheads and the aeration.
The babies are some of the most natural fish to feed of all egg layers. They prefer prepared food to live. It takes about two months for the baby fishes mouth to transform into the suction device, so while they are living in the water column to avoid the strong water movement, the adults like.
