Porcelain Crabs, with their fascinating and peaceful nature, are a great addition to any reef tank. They are an ideal species for beginner and expert aquarists alike, as they are easy to care for and maintain. It is important to note that they should always be kept in pairs and should be provided with plenty of live rock; any additional fish or invertebrates may bring harm to these gentle creatures. Furthermore, it is important to remember that they are 100% reef safe and will not damage your corals or other invertebrates.

The Porcelain Crab is a unique filter feeder that is an excellent addition to any home aquarium. They are constantly filtering the water for planktonic food, but can also scavenge for larger meaty portions. To ensure your Porcelain Crab is receiving the proper nutrition, provide it with small bits of fish, shrimp, or other meaty foods, as well as specially formulated foods for filter feeders. Additionally, supplementing its diet with algae-based foods can ensure it is receiving all necessary nutrients. Furthermore, to encourage healthy growth and behavior, it is important to give the crab a variety of food sources.
