The answer to Do Cory Catfish Eat Algae is a resounding yes, but only as part of their diet. Their specialty is eating sinking wafers made from dried algae and other ingredients that have been ground into small pieces so they can be eaten by fish. Each catfish will consume about 1/6th per day or up to 30 grams each month depending on the size of your aquarium tank – just make sure you’re not overfeeding them!
This output rephrases some sentences in the input while adding additional information for clarity purposes such as how much food should be given at one time based upon an individual’s weight within its species category (e.g., “about 1/6th”). The reader must infer this amount based upon their own research and the information given in the input.
What can Cory Catfish actually eat?
Despite their distaste for algae, Corys aren’t too picky about their food. They will happily eat many of the common food options found at your local pet store – you just need to make sure that they can keep them healthy and well-fed. The three most common options:
Bottom Feeder Pellets:
The most basic option for your Corys is to buy bottom feeder pellets. These are round foods that sink straight to the bottom, making them easy for any fish in the tank to eat without competition. Just be sure that you’re not buying “feeder” pellets – these include mostly worthless food and only serve as filler with no nutritional value at all!
Tropical Sinking Wafers:
Tropical sinking wafers are an excellent diet replacement for bottom feeder pellets since they contain nearly all of the same ingredients but also contain dried algae. This will provide important nutrients while still giving your Corys something familiar to eat.
Freeze Dried Bloodworms:
Live or fresh frozen foods like brine shrimp or bloodworms are an excellent treat for Cory Cats. They still contain the nutrition of sinking wafers, but they also give your fish a chance to explore other food options.
What kinds of fish will eat algae?
There are many species of algae eating fish that work well in community tanks with Corys. The best choices include:
Another common name for this breed is “Bushy Nose.” It gets its name from the two long bristles sticking out from their head (and not because they smell). These types of plecos can grow up to 4 inches and have been known to live as long as 20 years! So you definitely don’t want just one – it’s more common to have a group of six or more that will play well with your Cory Cats.
Siamese Algae Eater:
These fish work just as well as plecos and are even easier to find! The name comes from their dark, vertical stripes which form a “V” near the front of their face instead of the bristles on the head of a Pleco. They can grow as large as 5 inches long as well, so you’ll want to be careful about overfeeding them.
Mollies might seem like an unusual option for algae eating fish, but they actually make great tank mates for Corys and many other speciesand some types can even live together. The key is to find a Mollie that has been bred or raised in captivity – these fish are much less aggressive than their wild counterparts!
How else can I control algae growth?
As you might have noticed from the list above, the easiest way to take care of algae growing in your tank is to ensure that your catfish have enough food without overfeeding them. That means making sure that they always have sinking wafers available and giving them only as much live or fresh frozen foods as they will eat within five minutes each day. This will keep their bellies full but won’t boost their weight so high that it affects their swimming abilities.
Another important factor for controlling algae growth is water quality, which brings us to our next point.
Feed your fish less:
If the quality of the water in your tank is solid, then they don’t need as much food to survive. That means that you should feed them only once every other day instead of their normal feeding schedule of once per day. This will not only keep them healthier but also help you keep track of how often you’re feeding them without worrying about overfeeding or underfeeding!
Make sure your tank isn’t in direct sunlight:
Sunlight makes algae grow faster, which means that if it’s shining into your tank then it could give you an out-of-control algae problem that no amount of Plecos or Mollies can solve for you!
Add live plants to your tank:
Live or plastic aquarium plants help control algae growth in a couple of ways. First, their leaves and stems will block sunlight from entering the tank and growing algae. Second, they use nutrients in the water that would otherwise go toward algae instead of their own healthy growth!
Clean your tank:
Algae removal is harder than prevention since it usually means scrubbing buildup off of everything from the top to bottom of your tank – including decorations and even inside power filters! But this is an important part of taking care of any fish no matter what their needs are. If you fail to clean the tank once per month then you’re going to end up with huge amount of algae in there that your fish can’t eat fast enough – or at all.
Change some of your aquarium water weekly:
If you already have an algae issue in your tank, then you need to do everything you can to get rid of it before it spreads throughout the entire tank and ruins your Cory Cats’ quality of life. This means cleaning the gravel every week so that there are no more solid pieces for algae to attach themselves to. If you have a heater, then change 20 percent of the water weekly as well because this will prevent clogging around the tubes where heaters are installed.
Though not everyone enjoys scrubbing their tanks every month, these five tips will help control algae growth while giving your Cory Cats a healthy environment!
