There exists a wide variety of plecos in the hobby, so it is important to research the specific species you are interested in before purchasing. 

Common plecos can grow to be over 24 inches (60 cm) in length, so If you have a really big tank (80 gallons) then you can keep the common plecos.

Furthermore, it is important to note that not all plecos are suitable for the home aquarium. 

Some species, like the common pleco (Plecostomus plecostomus) are known for their voracious appetites and can quickly decimate an aquarium’s population of plants and other fish.

However, to keep them bristlenose plecos healthy you will need to feed them high quality foods. Feed them blanched zucchini or cucumber once every week and regular commercial food on a daily basis.

Things That You Need to Maintain Your 10-Gallon Tank


Did you know that tap water contains chlorine and/or chloramine to make it safe for human consumption? However, these chemicals can be harmful to the fish and invertebrates in your aquarium. That’s why it’s important to use a dechlorinator to make the water safe for your aquatic pets.

Personally, I would recommend Seachem Prime in my tanks because it’s more concentrated than other brands, which means I don’t have to buy it as often. You can find this dechlorinator just by clicking here.

Can I Put a Pleco In a 5 Gallon Tank?

Yes, you can! In fact, there are a few different species of dwarf plecos that can live in a 5 gallon tank. But it is not recommended to keep multiple plecos on a 5 gallon tank.

You can keep a single dwarf pleco in a 5 gallon tank for a few days. But transfer it to a bigger tank when it gets bigger.

However, you should make sure that you get a species that has a smaller size in mind. 

For example, the Bristlenose Pleco (Ancistrus sp.) is a small pleco that needs a tank with a minimum capacity of 10 gallons. Another example would be the Gold Spot Dwarf Pleco (Hypostomus sp.), which needs a tank with a minimum capacity of 12 gallons.

What Is The Biggest Pleco?

The Pleco species known as Liposarcus anisitsi is widely considered to be the biggest Pleco on the planet. This can grow to a maximum length of 17 inches. And according to some sources, they can also grow up to a whopping 30 inches. 

The second-largest pleco is Hypostomus plecostomus, also known as common pleco. These plecos grow up to 20 inches, it’s available everywhere. 

Another contender for this title is the Leopard Pleco. And this species can grow up to 20 inches in size. However, in contrast to Liposarcus anisitsi, this species has a darker, orange-brown color.

Can I Have 2 Plecos In The Same Tank?

Sure! There are many species of Plecos that can be kept in the same tank together. However, you should make sure that the species are not very aggressive to each other. 

For example, if you get 2 species of Plecos that are known for their size and aggression, then you should only keep one of them in the same tank. The other one should be kept in a separate tank if it is even possible.

As a side note, I have written an article describing the problems regarding keeping multiple Plecos in the same tank. You can check out this article by clicking here.
