wow id never go back to that LFS... and id tell anyone walking in there to leave as well.
i would not add any nudibranch to the system unless you know how to properly care for them. most , if not all nudibranchs are VERY specialized and eat only very specific food items that we as hobbyists can rarely provide. in most cases, the nudibranchs do their job and then starve to death. in some instances, the dead nudi can release a toxin that has tank-crashable potencies. it is also irresponsible as a hobbyist to purchase one just for its task with the idea of "i will just trade it to somebody else who needs it when i am done / trade it to the fish store". Obviously there is no guarantee of another hobbyist that is in demand or LFS that will take it back.
