If you are new to keeping the species or new to the fish keeping hobby in general then try to focus your efforts towards poor water parameters and issues with the yellow tang being stressed.

Symptoms of a yellow tang being stressed include a loss of appetite, decreased activity levels, the fish hiding often, and a change in coloration.

If you notice any of these symptoms in your yellow tang then it is important to make sure that the water parameters in its tank are correct and that there are no other fish bullying or harassing it.

If you think that poor water parameters may be the reason your yellow tang is not eating then the first step is to check the water parameters in its tank.

Ammonia, nitrites, and nitrates are common issues but the pH of the water can also be difficult to maintain at a steady level in some tank setups too, especially if you are new to keeping fish.

How Do I Get My Yellow Tang To Eat?

The best way to get your yellow tang to start eating again is to mimic its natural environment as much as possible.

This means making sure that the water parameters in its tank are correct and stable, providing plenty of hiding places, and ensuring that there are no other fish bothering or bullying it.

What Do You Feed A Yellow Tang?

Yellow tang are omnivores and therefore their diet is not limited to one type of food. In the wild, yellow tang feed on a variety of small marine creatures, including zooplankton, shrimp, and crabs.

They also consume a fair amount of plant matter, such as algae and seaweed and there are many commercial fish foods on the market that are suitable for yellow tang.

Although live food can be expensive for a yellow tang diet, it is often the best way to get a yellow tang that is not eating to start eating again.

If you cannot afford to feed your yellow tang live foods then there are many alternatives available with freeze dried and frozen marine creatures being a great choice.

The suitable flake and pellet based fish food are also available with most yellow tang eating them if nothing else is available.

Some yellow tang will also eat nori seaweed sheets that are cheap but others won’t even touch them. This are packed with vitamins and minerals though so it is definitely worth offering them to your yellow tang to see if they will eat them as they are a great way to keep your yellow tangs colors bright while also offering some natural parasite protection too.

How Often Should I Feed My Yellow Tang?

Yellow tang should be fed once or twice a day depending on what you are feeding them and the amount of food you intend to offer.

Although they will often graze on algae and other food sources in their tank if they are available. It is important not to overfeed yellow tang as this can lead to health problems, such as obesity, and it can also pollute the water in their tank.

If you are new to keeping yellow tang then it can be difficult to work out how much you should feed your fish as well as how often. A good rule of thumb is to offer them as much food as they can eat in 3 minutes and then remove any uneaten food after this time.

Not only does this simple and easy to follow rule help prevent your yellow tank from gaining weight but it also works wonders for your water parameters too.

How Long Can A Yellow Tang Go Without Eating?

Although yellow tang are tough fish, they can only go without food for a maximum of 3 days before they start to experience health problems. This is why it is so important to get your yellow tank eating again as soon as possible if they stop eating for any reason.

The longer your yellow tang goes without eating, the more serious the problem can become and the more likely it is that the fish will perish. If you can get your yellow tang eating again within three days then it has a high chance of making a full recovery with minimal long term problems.

If it takes longer than three days to get your yellow tang to start eating again then the odds can quickly stack up against your fish.
