Care of German Blue Rams?

I have 2 pair in a 34 gal tank....VERY heavily planted. They have never looked better......
 
Hi
I would like to try again but feel that I should change something but at a loss as to what lol. The one survivor is doing well but then the others appeared to be doing well and never showed signs of distress . Only symtom was going off food
and then hiding always died during the night and the period of going off food to death was less than a day
interesting that the survivor is from the original stock ..my only guess is that I got bad stock
Good luck with yours !!! gary
