This specialized eater provides an effective natural control of flatworms in the aquarium. It uses a tube-like proboscis to suck up the flatworms and does not require any additional food sources. Nonetheless, it is sensitive to changes in water conditions and requires a high level of expertise to maintain. It is important to keep in mind that this species does not have a long life expectancy, so it may not be suitable for aquarists who are not experienced in keeping this type of species. Furthermore, due to its sensitivity to water changes, it is important to ensure that water parameters remain stable for the health of this species. Finally, it is essential to monitor the aquarium to make sure the species is receiving enough flatworms for its diet.

Spawning is a natural process for this species when multiple individuals are kept together, so it is prudent to create an optimal environment for them in order to maximize the chances for successful reproduction. Additionally, it is important to stay informed on the latest recommended practices for successful rearing of the larvae. With the right conditions and proper care, it is possible to achieve a higher success rate in raising this species.

The Blue Velvet Nudibranch should be acclimated using the Drip Method. It should be avoided if it is being kept in an aquarium with pumps and drains as it can be harmed. It is sensitive to high levels of nitrate and will not tolerate copper-based medications.
