Sea Slugs/ Nudibranchs?

[Mak]

Hello,
Found these 2, 3 millimeter long by 1 millimeter wide slugger guys. They are a reddish pink without shells, and appear to have some kind of spikes or something like that on there backs. There are 2 of them and they appear to be just a tad bit different, probably a male and female. Went to the Sea Slug Forum and could not id them( probably cause they are babies? ). So what should I do? Should I get rid of them all together or should I put them in my Ref? :confused: .
