I have a group of these now, they are continually spawning. The "croaking" sound they make is fascinating, and indicates the males are either "threatening" or "enticing" another fish. They pygmy makes a grating sound, the true Croaking Gourami is a bit different.
A group of 3 pygmy sparkling gourami could manage in a thickly-planted 10g tank; I wouldn't suggest more. They must have plants, thick plants. They do not need "swimming room" as such. They spend their day browsing among plants looking for food bits. They are bubblenest builders, thought the bubblenest is a fairly poor effort, only a half dozen or so "bubbles" but it is sufficient. I have 7 different size fry in my tank at present that have survived from various spawnings. And thick plants provides "space" as the males, like all gourami, are territorial, which is why I suggest 3 or maybe 4 in a 10g.
Plants like Wisteria (Hygrophila difformis) are ideal and they are multi-branched. Floating plants are a must, Ceratopteris works fine, as will Wisteria allowed to float. These are in our profiles, click on the shaded name. And so is this fish, Trichopsis pumila. Make sure this is the species, not to be confused with the larger Croaking Gourami.
