While fish can eat chocolate, it’s not recommended to feed them chocolate since it’s not part of their natural diet. Chocolate contains sugar and cocoa. These are poisonous to fish and don’t have any nutritional value. Chocolate also contaminates the tank water. Polluted water is harmful to fish.
Fish are very flexible and consume a wide variety of food that you can never imagine. Just like any living being, they also need vitamins and minerals to thrive. However, some food like chocolate may prove hazardous to their health. So, let’s now see why chocolate is not good for fish.
Why Is Chocolate Bad For Fish?
Chocolate is not a natural diet of fish. They do not consume chocolate in the wild.
Any diet that is not a part of their natural environment is difficult to digest.
Chocolate is bad for fish because it contains sugar, which is poisonous to fish.
Chocolate melts in the water and contaminates it. Polluted water is one of the primary reasons for the untimely death of fish.
Besides, chocolate contains cocoa, which is also not good for the health of any fish.
Feeding chocolate will not kill the fish immediately.
However, if you continue feeding chocolates to your fish, it will most likely hurt their health in the long run.
Besides, chocolate doesn’t have any nutritional value. So, it is always better to feed your fish the diet that best suits them.
Can Sugar Kill A Fish?
Yes, sugar can kill a fish. If you add sugar to the tank water, it will feed the microorganisms such as yeast and bacteria.
These microorganisms will produce toxic substances such as alcohol and carbon dioxide.
These are not the good bacteria that carry out the nitrogen cycle.
On the contrary, an increase in these bacteria will lead to cloudy water and lower oxygen levels.
If you have a tank with a good oxygen supply, the bad bacteria in the water will convert the sugar to carbon dioxide and water, using up lots of oxygen from the water.
On the other hand, bacteria will convert sugar to alcohol or lactic acid with a poor oxygen supply.
Sugary water also largely affects the water’s ability to hold the dissolved oxygen.
Oxygen is necessary for fish respiration. Poor oxygen supply will suffocate your fish.
It will start gasping for air and will eventually die.
Also, an increasing amount of sugar in the tank water may cause a significant drop in the pH level, proving to be lethal for your fish.
Sugar is osmotic. It will draw all the water out of the bacteria cells, including the fish and plants.
All your fish and plants will then die due to dehydration.
What Human Food Can Fish Eat?
When it comes to feeding fish, a lot of human food is safe and nutritious.
However, it is equally important to understand the dietary requirements of your fish and feed them accordingly.
Just like humans, fish are broadly categorized into herbivores, carnivores, and omnivores.
If you ever find yourself with a shortage of fish food, you don’t have to panic.
There are plenty of healthy alternate foods available at your home that can serve as emergency fish food.
- Many herbivore and omnivore fish love to munch on vegetables like spinach, peas, lettuce, carrots, zucchini, and cucumbers. You can boil these vegetables and cut them into tiny pieces to feed your fish.
- You can feed fish pellets like tilapia and cod to carnivore fish. If you feed frozen fillets, make sure that you first defrost them and then feed them to your fish.
- Talking about meat, beef-heart is a good option as it does not contain too much fat.
- Smaller fish, including shrimps, devour hard-boiled egg yolks. It’s a good idea to feed egg yolks as an occasional treat to fish. However, it would help if you don’t overfeed it because yolk particles make the tank water murky.
What Kind Of Food Should Be Avoided For Fish?
Most of the fish are not picky eaters. They eat pretty much anything that is served to them.
However, there are certain foods that you should avoid feeding them. Harmful food can make the fish sick and unhealthy.
Fat is toxic to fish. It is best if you avoid feeding meat that is high in fat. Fish will find it difficult to digest.
Regularly feeding meat such as pork, beef, or even chicken scraps can cause fat build-up around a fish’s heart.
Bread is another food that you should strictly avoid feeding your fish.
Bread contains yeast and gluten that causes digestive problems.
Consumption of bread can cause several health issues such as bloating, constipation, and swelling in fish.
More than 3% of fat can be harmful to the liver and reproductive organs of herbivore fish.
Similarly, for carnivore fish, the fat consumption quantity should be up to 6%.
Another concern is the water content in fish food.
The water content in some of the dry fish food ranges from 5 to 15%.
If the water content is high, the chances of food deterioration increase.
Dry fish flakes can absorb moisture from the air.
This can lead to bacterial action and will convert the dry flakes to moist dust.
To avoid this, you can store dry foods in tightly sealed containers.
If you regularly feed live food to your fish, you need to ensure that it is clean.
Any live food can have a disease that can easily spread to your fish on consumption.
Also, you should remove any leftover food from the tank before the water gets cloudy and harms the fish.
