I currently have a 40 gallon tank stocked with 11 ember tetras, 10 cardinal tetras, and 5 oto catfish. I'm looking to add a top swimmer to my tank. I can't decide which would be a better fit a betta or honey gourami. I can easily find a betta, but they're always stuck in small cups in Petsmart/Petco and i don't want to possible pick a sick fish. Honey Gourami on the other hand are much harder to find.
