. . .
I wouldn't have CHOSEN to have so many males (don't trust petstore people
but so far I have no regrets on species choice (crossing fingers on DG Disease, probably regret that one day). I do have a LOT of plants and
caves and
driftwood-laced-with-guppygrass-that-I-cannot-Remove, and I think that is one of the most important factors to consider with gourami.
I do also keep glowlight tetras in the tank, and there has never been even a moment of concern.
My only real struggle was when I had only half the top of the tank covered in
duckweed.... the powders would squabble over who gets to hang out under it. But my duckweed has since taken over completely and there is no more squabbling... just constant disposal of duckweed xD
I think the most interesting part of the gourami's behavior is that when there *is* antagonization, it is never between two different species. The male pearl will sometimes poke the female if she's collecting his scraps at mealtime, the powders will occasionally run into eachother while patrolling and *politely* ask eachother to move along. Otherwise, the powders just nibble at the duckweed and the pearls are diving in and out of tunnel caves all day while side-eyeing skrimps.
The honey gourami literally never interact with anything except the plants. They love the plants...
Edit: I thought of another EXTREMELY important note.
Pearl Gourami can be super skiddish. Mine are not, anymore; but when they were first placed in the tank, they were like deer. One of the pair (I believe the female) bonked the glass one morning when I turned on the light and that was... oof. I felt quite bad. So just be wary.
