Bta not attached

[Zos4me]

So 2 weeks ago I added 2 btas that were attached to a rock at the lfs.they have seem to be fine .they moved 2 times and settled. I got a little cyano around them so I went to move the rock they were on and one fell off. Is there something possibly wrong or did i just tick it off and it jumped ship
Thanks

Photos and parameters please.

How old is your tank?

Almost 6 months

Almost 6 months

Would be helpful to know your water parameters and the parameters the nems came from.

Are you 6 months new to reefing as well?
Judging by your profile creation date i would assume not.

This is my 3rd or 4th tank but first less than 40 gallons. I honestly haven't been testing other than salinity. If a coral seems off I find out why. I haven't had any issues except occasional cyano in small areas.which after a water change go away. I use only nitrisea water. I don't mix my own and i do have an ro do system for ato
