Freshwater Pom pom crabs are a freshwater crab that is native to Southeast Asia, Taiwan & Japan. They can grow to be up to 2 inches long and have a very interesting diet. These crabs feed on algae, plankton, small insects, and detritus (dead organic matter). This makes them an important part of the ecosystem because they help keep the water clear by eating all the dead material floating around! In this article, we’ll explain the pom pom crab freshwater feeding habits & diet in details.

Overview

Pom pom crabs are freshwater crustaceans that live in rivers, canals and lakes. This group of crabs is different from other freshwater crab species because they have a feather shape on their claws instead of a pointed claw like most freshwater crab species.

Pom pom crabs feed primarily on algae but also consume insects, fish eggs and any small animals around the environment such as worms or larvae. There is a lot of information about this wonderful specie that we haven’t yet acknowledged. But through the process of observing with crab keeping, we know that Pom pom crabs are not picky about their foods.

Fish Food & Treats for Bottom Feeder

Prepackaged fish food, such as fish pellets, are a great for pom pom crabs. They can be found at most pet stores and come from manufacturers that specialize in fish food. Fish pellets are great option if you’re keeping other species, in which they can share their food with pom pom crabs.

If you want feed pellets to your pom pom crabs, remember to choose the food that can sink – or known as bottom feeding food (pom pom crabs can’t swim through water, remember?). You can distinguish by finding the pellets for bottom feeder. Fish pellets such as Aqueon Shrimp Pellets or TetraMin Complete Diet Tropical Tablets for Bottom Feeders are perfect diet for pom pom crabs.

On the other hand, fish flakes are not suitable for pom pom crabs, as flakes will always float. Flakes are more suitable for top & mid feeding fishes.

Algae wafers

Algae wafers are slow sinking foods that are considered to be the most commonly used food for freshwater pom pom crabs & other crab species. They typically have a long slim form and come in two sizes, small or large. Algae wafers are usually made with a freshwater algae called chlorella that is rich in protein, chlorophyll & other nutrients.

Algae wafer is the perfect source of protein which helps promote healthy growth in freshwater pom pom crabs as well as provides essential vitamins and minerals when fed on a daily basis.

Algae wafers are typically used as a staple food but because they can be difficult to find sometimes and expensive when you do, it’s always good to have a couple of alternatives on hand for your crab.

Our recommended algae wafers for your freshwater pom pom crabs are Tetra Algae Wafers, HIKARI Sinking Wafers or our most favourite Aquatic Arts Algae Wafers. Algae wafers are more expensive than pellets, but they will provide more nutritions & vitamins for your precious pom pom crabs and other fishes as well.

If you choose to feed your freshwater pom pom crabs with algae wafers, make sure they are cut in half or quarters to make the food portion more manageable.

Live Feeds

Live feeds such as worms will likely provide your freshwater pom pom crabs with all their necessary nutrients they need – but this is not necessarily better because these organisms also carry diseases which might infect freshwater pom poms crabs.

Crabs are generally scavengers, not predators so chances of freshwater pom poms crabs eating live feeds is low but it’s still something you should be aware of and monitor the feeding habits closely when they start to show signs that they’re interested in hunting down food themselves which could be a sign of aggression.

Algea

In natural habitat, pom pom crabs will most likely to feed from algea growing in their freshwater environment. So it’s always ideal to fish pom pom crabs with live algea.

This is a positive sign because it means that the crabs are healthy and likely to thrive – but as mentioned previously, you need to be cautious of any signs of aggression which could also mean they’re not getting enough food from algea alone.

In every aquariums, there will always be algea. By letting pom pom crabs feed from algea inside you tank,you will have the benefit of controlling the amount of algea inside your own tank. Algea can be benefical in a medium quantity, but letting algea overgrows, that will be a problem.

Calcium supplements

Pom pom crabs just like any other crab, they will molt. Molting is the process in which they shed their shell. This happens to help them grow bigger and also helps them detach from any parasites that might be stuck on the surface of it.

Pom pom crabs need a lot more calcium than what freshwater can provide, it’s ideal to feed calcium supplements for your pom pom crabs once in a month.

Our favourite calcium supplements are Weco Wonder Shell Natural Minerals and SunGrow Shrimp Mineral Rocks.

Other foods

There are a couple of other options that you can give freshwater pom pom crab as well, such as: dried algae sheets, fresh green vegetables (broccoli, turnip greens), and even boiled eggs.

Considered an omnivore species by nature, freshwater pom-poms will eat just about anything that you give them.
