But also, they should never be placed in a tank with sedate fish--and all gourami are sedate. The gourami's long fins are too much of a temptation, and the Gourami is not prone to fast escapes so it will be highly stressed.
I do not consider Serpae community fish. I know, sometimes they work, or do for a while; but you cannot change their inherent nature and at some point it is more than likely to reveal itself. The Tiger Barb is similar. And as you say, these fish are commonly available and stores sell them un-knowingly. It pays to research any fish before you get it. Our fish profiles are a good start.
In your 30g, I would suggest you have two options: only Serpae Tetra (get more of them), with some substrate fish [the hatchets may or may not be attacked, I would remove them for their own sake]. Or return the Serpae and build a community of compatible fish.
Great advice. I would recommend returning the Serpae Tetras & getting Cherry Barbs, which are very peaceful & beautiful to look at. I also had a bad experience with Tiger Barbs nipping the fins of my Three Spot Gouramis. I returned the Tigers and replaced them with Cherry Barbs & Von Rio Tetras. So far so good....................
