I'm considering adding one to my barb tank, which has been stagnant after the issue with the torpedo, and most of the fish I want to add back again are out of season... the kisser gourami in my Hillstream tank, has been an ideal tank mate in that tank, but both the barb tank, and the Hillstream tank's temperatures are on the cool side of what most gourami's are listed at... the one I'm currently looking at for the barb tank, is a Pearl ( Trichopodus leerii )... both tanks listed here are cool water tanks, running on the low 70's F.
