Do Algae Eater Fish Need Food?
If you’re wondering whether algae eater fish need food, the answer is both yes and no. These fish are known as “opportunistic feeders,” meaning that they will eat just about anything they can find. This includes algae, of course, but also small invertebrates, detritus, and other organic matter. In the wild, these fish are constantly grazing on whatever they can find, and in captivity, they should be offered a similar diet.
That said, algae eater fish don’t actually need to eat food all that often. In fact, if there’s plenty of algae in their tank for them to graze on, they may not eat anything else at all. It’s important to offer them a varied diet, however, as this will ensure that they’re getting all the nutrients they need.
Do Algae Eaters Eat Fish?
One of the most common questions people have about algae eaters is whether or not they eat fish. The answer to this question is a bit complicated. In general, algae eaters are not interested in eating fish and will even leave them alone if they’re well-fed.
However, there are always exceptions to the rule, and some algae eaters may decide to nibble on fish if they’re feeling particularly hungry. This is more likely to happen if there aren’t enough algae in the tank for them to graze on. So it’s important to make sure that there’s plenty of food available for them.
In addition, some algae eaters may view fish as competitors for food and may become aggressive toward them as a result. This is more likely to happen if the tank is overcrowded, so it’s important to make sure that there’s enough space for everyone.
Do Chinese Algae Eaters Eat Plants?
Chinese algae eaters are a type of fish that’s particularly known for eating plants and are used in aquariums to control algae growth.

The only time you need to worry about Chinese algae eaters eating plants is if the plants are dying. In this case, the algae eaters may view the plants as a food source and start to nibble on them.
