I have had honey gouramis in my 20 long. One was a sunset, the other a red. I really like/liked them. The sunset passed a week ago out of nowhere, but the red is doing well. I'm not sure they do well with other labyrinth fish. May have been a culprit in the death of the sunset (stress related?)
Not super colorful, but peaceful and I like their demeanor. Fun fish to watch just scrounging the bottom for whatever they eat. Mine would only spit the micro pellets out, never actually eat them. They can be partial to eating some plants, especially my Bacopa carolinianas. He is especially fond of cucumbers.
+1 to the recommendation of the white clouds. I had 5 and they were skittish. I got 5 more and they are looking very much more comfortable.
