keeping flat worms in a tank

Question
Is it possible to keep the beautifully colored saltwater flat worms in a tank?  If so, how much would it cost to buy them and maintain them?  Can they be kept with other fish?

Answer
Jennifer,
By flatworms I assume you mean the nudibranches.  They can be kept in reef type fish tanks but most species are extremely difficult to keep and even then their life expectancy is limited to months.

Most species will retail between $25 and $75 each.

They are a nice temporary addition to most fish tanks that are able to house them.

Best of luck with your tank!
