Yes did you cycle your tank properly??
If you didn't the "CYCLE" could take months!
If you do it right you should be able to keep softies no problem..
As for your Pulsing Zenia (spelling?) move it down to the bottom of your tank and in low flow for a few days and see what happens..
BTW.. Get yourself some Melafix..
Everything (corals) should get a good ten minute dip with high concentrate mix of tank water and a capfull of melafix...
Good habit and keeps critters ( unwanted) out of your tank...
