[Xanubis]

Hey guys, im quite new to Seawater aquariums.

Today i bought 2 new corals in my local store. shopkeeper sold me these as 'easy to keep' corals '

After posting some pics on a national forum i got a feeling they sold me Dendronephthya or Stereonephthya sp

In case of Dendrone's i have a big problem keeping them... Id like your opinion on this matter.

and number 2

Kind regards
