Yes when I was planning to get another tank I was going to do a small "river" set up for the loach but after this past year and surgery I can't keep up with 2 tanks right now so I may end up contacting my LFS to see if they will take the loach if I can't do the river set up. Anyhow the Gourami is a dwarf blue. I believe he is max size, he looks like he is 2 or maybe 3 inches in length and plumped up a bit from his diet.... He has been with us for almost 2 years now and I am not sure how long the LFS had him to begin with, I would assume the Gourami was only a few months at most when we got him. If that...depending how long they take between transport to the lfs and such. I know my LFS quarantines all their fish for about 1 week to 2 weeks before they are able to be sold.
Anyhow that is where I am at...
