Hi all, I have 2 sparkling Gouramis in a 29gal peaceful community. I am setting up approx a 20ltre tank for shrimp, planted and wood also, just to sit on my computer desk for when I'm bored on it. Is it a good or bad idea to put these 2 gouramis in too? I know they are tiny but is this too small? It has a built in undergravel filter system also so that is covered and I have a heater in it. Thx in advance.
