The 5 Best Algae Wafers For Plecos

Plecos need to eat well too, so let’s take a look at the top five algae wafers for plecos right now. Keep in mind that they are all going to be similar, but all good choices nonetheless.

1. Hikari Algae Wafers

These algae wafers are made with tons of algae, vegetable matter, and cultured spirulina as well. In other words, it really is quite the perfect piece of nutrition to feed your plecos.

It is more than healthy enough and contains a whole lot of plant matter, which plecos love to eat and need to survive. Hikari Algae Wafers are actually made with a whole lot of stabilized vitamin C in order to help your plecos have a healthy immune system and to reduce levels of stress as well.

When it comes to feeding your pleco, Hikari Algae Wafers are probably one of the healthiest options in our opinion.

2. Aquatic Foods Inc. Wafers of Algae

Aquatic Foods Inc. Wafers of Algae come in a lot of variety, at least in terms of size. If you only have one pleco, go for the ¼ pound, ½ pound, or the 1 or 2-pound bag, but if you have lots of mouths to feed, these things come in packages up to 25 pounds, so you can stock up real well.

Beware that some of these wafers may sink, some may take longer to sink, and some may float. It is kind of a guessing game, but other than that, these are ideal to feed plecos, and for a number of other algae-eating fish and aquarium critters too. Aquatic Foods Inc. Wafers of Algae are made in the USA and made with 100% all-natural ingredients, both things we appreciate. Moreover, there is a high level of vegetable matter included here, and of course a whole lot of algae too. They’re also made with lots of Spirulina, plus they contain a ton of Vitamin C.

The result here is a tasty wafer that plecos generally love, one that is easy to digest, provides plecos with all of the necessary nutrients, and helps to keep them colorful, happy, and healthy too. It is a great food for maintaining low-stress levels and a strong immune system.

3. Tetraveggie Algae Wafers

These are known as 2 in 1 concentrate wafers, which is because they are loaded to the brim with various vitamins, minerals, and other nutrients to keep your pleco healthy. This stuff comes complete with Biotin, which helps to maintain a strong metabolism. It also comes loaded with Omega 3 fatty acids, which is nice because it helps fish get energy, calories, and helps them grow strong.

Between the algae and the other plant matter that is included in these Tetraveggie Algae Wafers, there is also a lot of Vitamin C and other nutrients which serve the purpose of creating a strong immune system and reducing stress in the fish. It is also worth mentioning that these wafers are very high in fiber, which helps plecos digest them with ease.

What is also nice about Tetraveggie Algae Wafers is that they are made with a so-called clear formula, so they should not cloud the water. Moreover, they are made to sink, which is good for plecos as they are bottom feeders for the most part.

4. Aquatic Arts Algae Wafers

Now, these Aquatic Arts Algae Wafers are quite unique when compared to the others on this list. The reason we say this is because the other options did not really contain much protein, which certainly is not the case here. These Aquatic Arts Algae Wafers actually contain roughly 30% protein, which comes from plants and meat sources.

Yes, this is the first option on our list today which actually has meat in it, mainly from fish, shrimp, and krill. Plecos are not purely herbivores, so this is fine, but some plecos may not particularly like the taste. With that being said, these wafers have a high content of algae, kelp, spirulina, and veggies too, and they are indeed mostly made of plant matter, which is what plecos need.

The fact of the matter is that these algae wafers do contain a lot of vitamins and other nutrients to assist in energy requirements, healthy growth, coloration, and a strong immune system. However, they don’t contain quite as many of these nutrients as the other options we have looked at, but they are higher in protein.

It is a bit of a tradeoff to think about. Keep in mind that these things are designed to sink, but if left in the water for a while, they will break up and discolor the water.

5. Api Algae Eater Wafers

These are sinking wafers that are made for herbivorous and omnivorous bottom feeders. They sink fairly fast, which is nice. Now, keep in mind that these things are made mostly with algae, vegetable matter, and some omega-3 fatty acids too. The previous option we looked at was really the only one on our list today that had animal proteins in it, but with that said, plants and algae do still have protein in them, so that should be more than fine.

These wafers are made with lots of omega 3 fatty acids, vitamins, and other nutrients that are found in algae and veggies. In terms of maintaining a bright coat, maintaining a healthy immune system, keeping stress low, and aiding in proper digestion and metabolism, these Api Algae Eater Wafers are a great option to go with no doubt.

Now, the packaging here does say that these things will not cloud up the water, which is true for the first few minutes, but if many of them stay in the tank uneaten, cloudy water will be unavoidable.

Buyers Guide: How to Pick the Best Algae Wafers for Plecos

Pleco Diet Essentials

When it comes down to it, plecos are easy to feed and to please. A rule of thumb to keep in mind here is that plecos need around 85% plant matter and 15% animal protein for a proper diet.

Important: Getting The Right Balance

A lot of people, even the pros, make the mistake of saying that plecos need 15% protein and 85% plant matter. But this is wrong because plants have protein too, that 15% is about ANIMAL protein, or in other words, meat, such as from other fish, shrimp, and krill. Either way, as long as you don’t exceed 15% or 20% meat/animal protein, you are on the right track.

Do Plecos Like Algae?

Yes, plecos love algae, but your fish tank probably won’t provide them with enough of it, which is why you need to feed them algae wafers. You can also feed your plecos some blanched veggies like lettuce, cabbage, carrots, cucumbers, and peas, as well as bloodworms, krill, and other small aquatic animals.

Keep in mind that plecos do need some fiber, so looking for a wafer that is high in fiber is ideal. If you don’t give them enough fiber, you might want to insert a piece of driftwood into the tank, because the plecos will eat some of that driftwood due to its high fiber content.

How Do I Know If My Plecos Are Underfed?

If you notice that your plecos are eating your aquarium plants, it is a surefire way to tell that you aren’t feeding them enough, especially plant and vegetable matter. Feed your plecos twice per day, and make sure to not overfeed them.
