If you are wishing to bring color to your aquarium, then you should be looking for the dark grey fish with vibrant red/orange fins. This is the Rainbow Shark. Yes, you imagined right. These do resemble the shark with their upright dorsal fins. Otherwise, the small freshwater fish has a flat stomach with a pointed snout. The Albino rainbow Shark is a variety with white body. The appearances of these tiny aquarium fish may be deceptive making it look a little timid when young. But the aggression goes up as it matures.
Knowing the Rainbow Shark fish behavior
Knowing the behavior of the fish is imperative especially when the word ‘shark’ is pinned with the name. Rainbow Sharks being the territorial types may cause behavioral problems like aggression and dominance as they mature. Such behavior can include biting, chasing and head-and-tail butting. Planning their tank-mates is now very necessary.
These are also great swimmers. It is great to see them swimming across the fish tank. But that is not what they do all the time. They tend to hide a lot during their growing years. And they also like to dwell at the bottom eating the algae growing there. These are the aquarium cleaners.
Knowing the behavior helps in planning and placing the right things in the aquarium for the fish. If we find pleasure in seeing the fish swim, then we should also ensure that it enjoys its swimming as well.
Size of the aquarium
As rainbow sharks are active swimmers, they would not feel cool in a small aquarium. So ensure that there is enough space for swimming for the adult ones. There should be enough horizontal space.
Rainbow sharks are territorial in nature and like to hide a lot. So there should be enough hiding places in your aquarium like the rocks, caves, driftwood and even bushes.
Layering of the aquarium
Sand should be the first choice if you do not wish to harm the creature. These Rainbow sharks are from sand rich Thai rivers, so sand as the substrate would make them feel at home.
Rainbow sharks survive well in the following conditions: 75ºF to 81ºF; pH of 6.5 -7.5 and water hardness 5-11 DH. The lighting inside the tank should be kept at minimum with moderate water movements only.
Choosing the tank mates with Rainbow Shark Fish
It is not advisable to keep more than one Rainbow Shark together especially the adult ones. Choosing the tank mates for the species should also be done very carefully. The other freshwater species that dwell in the middle and upper parts of the aquarium will give a calm atmosphere inside the tank.
Rainbow Shark fish feed and diet
You really do not have to worry about their food and diet. They are not the fussy ones. They are omnivores and feed on a variety of food that sinks to the bottom of the aquarium. Flakes, pellets, vegetables, frozen meat and live food can be easily given to them.
Rainbow Shark fish are a joy to the eyes and an ‘easy to take care’ fish provided you look into their tank requirements.
