These days, an increasing number of people pick sucker fish to feed in their homes. What do sucker fish eat? Not everyone knows how to take care of them properly. If you are one of them, this content is for you.

Let’s come here to get more knowledge and tips to enhance your lovely pet’s life in the coming days.

What is Sucker Fish?

Suckerfish, called Plecos, belong to one of the popular creatures to raise in home tanks or aquariums. Observing them eat with their cool mouth or watching them hit themselves into glass surfaces has recently become many people’s interesting habits.

Thus, more and more people keep them as their pets. Suckerfish may grow up to approximately 1 meter (3 feet) long. The most notable species of Plecos are bigmouth buffalo, which have a maximum weight of 36 kg (around 79 pounds).

The root of the “suckers” name stems from their cool lips that are quite thick and allow the fish to adhere to the lower side of freshwater.

Most species of Plecos survive in lakes or streams across the USA, especially North America. Outside of these areas, the rest of their population has been discovered in China and Russia.

What Do Sucker Fish Eat?

When it comes to giving food to these Plecos, it isn’t hard. In the abstract, they are omnivores, including insects and small fish. Yet, for the most part, plant matter and algae are their crucial food.

This has built a significant role in controlling the algae of suckerfish, which is one of the main reasons many people want to raise them in their home tanks. They will rummage a tank from top to bottom to seek some tasty algae to eat.

Besides, even leftover food from other fish becomes part of their diets. There is a truth that most home aquariums don’t produce almost enough plant or algae to give a well-fed diet to suckerfish. Thus you need to provide more aliments for their meals.

Algae wafers and shrimp pellets should be the first place in the favorite food list for suckerfish. In addition, you can find their diets even in your kitchens, such as a fresh sweet potato, melon, zucchini, broccoli, lettuce, and cucumber.

Diving all the way down to the tank bottom to enjoy their meals is Plecos’s dietary habit. Hence, if you don’t want them to skip their meals, you need to make sure that your food being prepared for them can sink to the bottom.

Furthermore, bear in mind to remove discarded food from your aquarium every day. Otherwise, the water has become murky and created some unwanted natural substances that impact the suckerfish’s indoor habitat.

Even worse, smelling nasty might derive from missing clean excess food out of your home tank. By and large, feeding suckerfish is around two times per week, yet which food it is that might change feeding frequency.
