How long does it take for them to be full grown? I bought two small ones and lost one in QT within first few days. Wondering how long it will take the little one left to become full size. Also, if I replace the lost one with a medium size one will the two have any issues with one another or will they adapt fine despite size/age difference?

PJs are docile fish and do not fight with each other or others in the tank. They have a pecking order but it is primarily posturing not actual fighting. I have had the same pair for 4 years and they are full grown. Probably took 2 years to get full grown.

Agreed. Adding another one shouldn't be an issue, even if a little different in size.
They are a slower growing fish. A year and a half to two years is about right for growth.

I have one and he is very peaceful. Has not picked on any members added after he came to live with me 
Thanks! Just left LFS and the current batch they have was even a tad bigger than the last batch they had. But they cost less than the other LFS so I got two mediums plus my small. Hopefully they don't bother the small guy but I figured in case they do at least I'll still have the 2 I wanted.
