Feeding
These fish have special requirements with feeding. They spend their day pecking at the sand beds and rocks grazing. A mix of frozen, live and algae based foods is required.
- These are omnivores
- A varied diet made of predominantly vegetable based foods is a must to help prevent the onset of HLLE
- They are fast eaters, ensure you are feeding enough for the entire tank and not just these tangs
- They will graze on algae, seaweeds, diatoms, detritus, and filamentous algae throughout the day and readily accept other foods at feeding times
- Live foods, frozen foods, flake and nori will all be appreciated.
Acclimatisation
Place your fish in the bucket and then drip acclimate for about 45 minutes at a rate of 3 drips per second. This should bring the fishes water parameters in line with your tanks parameters.
Once your fish has been drip acclimated, catch the fish with a net and place it gently into your tank. Do not put any of the water the fish originally came in, into your tank.
Care should be taken after adding the fish to ensure there is a tightly fitting lid on the aquarium at all times. These fish are known to be jumpers and they are more likely to jump when first introduced to an aquarium.
Can you keep the Orange Shoulder Tang with other Tangs?
These stunning fish are less aggressive and boisterous than most Surgeonfish (Tangs). They are generally considered to be compatible with most living beings commonly found in mixed reef aquariums.
If you are planning on keeping the Orange Shoulder Tang with other members of the Surgeonfish family, the Orange Shoulder should be the first of the Tangs added to the aquarium, in order for it to be allowed to establish it’s territory and find it’s bolt holes!
As long as you have a big enough and well established tank, these fish shouldn’t cause you any issues.
