Unfortunately, rainbow crabs are also prone to a number of common diseases and infections. It is important for aquarists to be aware of these potential issues and to provide the necessary treatment if their crab develops any of the following conditions.

One of the most common diseases seen in rainbow crabs is shell rot. This condition is caused by a bacterial infection that affects the crab’s shell.

To treat shell rot, the affected area should be cleaned with an antiseptic solution and a mild antibiotic should be administered.

Finally, rainbow crabs may suffer from parasitic infestations. These parasites can be identified by small white or yellow spots on the crab’s shell and body. Parasitic infestations can be treated with an antiparasitic medication.
