Category:Invertebrate Difficulty - Challenging
These inverts will be hard to keep in aquaria. Either because they're rare in the wild or endangered, or are only available wild caught and their locale has restricted access, or are very sensitive to water conditions, won't breed or difficult to feed in captivity, or too large to keep in a regular sized tank. If they are found in stores, they're likely to be expensive.
