Honey Gourami Behavior/disease/condition? Question

[MsDoolittle]

I am a little concerned with one of my little honey gourami. "She" tends to sit near the bottom and guard her side of the tank. They eat a varied diet with frozen bloodworms as a treat. I have had them for about 2 weeks already and the larger one really never acclimated to the tank. I had checked out the LFS store on several occasions first, all appeared to be active, no dead fish, no "iffy" fish either- so I brought a pair home.  The smaller of the two is really vibrant and active. The larger of the two swims around occasionally, eats and reacts to stimuli,such as being pestered by a shrimp or her tank mate.  
 
Larger Gourami(1.25 inch)
Color- same as when purchased, slightly paler than tankmate
FIns-WNL
Gills-WNL
Body- WNL no lesions/parasites
Feces-abnormal IMO, thinner than I would expect.

 
Tank conditions 1pm today:
Temp- 75
Water- clear
Aerator-ok
Filter- ok
Light- ok
Obs- ghost shrimp- active, small gourami-BAR, large gourami-QAR on bottom left
 
Last water test: yesterday, last H2o change, 2 days ago.
NO3- 0ppm
NO2-0ppm
GH- 25ppm
KH-40ppm
pH-6.8
NH- looks between 0-.25ppm**
 
Not sure if it I need look into diseases or if my tank conditions are off. Of course I am worried that it may be  DGD!! Any input/advice is appreciated!

Little honey gourami did not make it checked on it this morning- it was swimming. came back a few hours later and it was almost lifeless.
 
I have one gourami remaining, and his shrimp clean up crew. They all appear to be thriving and the tank/chemistry is WNL. Really really hoping the other gourami will be okay

I'm sorry to hear of your loss
 
Sometimes fish just die, could of been due to the stress of the move, sometimes we just don't know why they pop their clogs.

Thanks Metka. Just sad, I felt like I did everything I could.
