Your Silver Dollar Tetras are more commonly known as Black Skirt Tetras in my area, Latin name Gymnocorymbus ternetzi. They'd prefer some more of their own kind when you get a chance.
Keep an eye on your Kissing Gouramis. They get big and can get aggressive.
I found this info online :
The Kissing Gourami can reach a length of 30 centimetres (12 inches) and will naturally need a big aquarium. Keep in mind that the little Kissing gourami offered by the pet store can quickly outgrow a small aquarium.
Try to mimic the slow-moving, densely grown Kissing Gourami habitat in Asia when you set up the aquarium and include a lot of plants. Always use sturdy and fast growing plants in the Kissing gourami aquarium, since sensitive plants will not tolerate being grazed by the fish. Java fern and Java moss is recommended.
Kissing gouramis can be fond of digging and this is naturally a problem since they should be kept in planted aquariums. You can prevent digging by using gravel and stones with a large diameter as aquarium substrate. This will also provide algae with plenty of surface area to grow on.
so yours may become an issue for a planted tank.
Other Gouramis are plant safe. But Gouramis, like their cousin the Betta, may not like each other. Lucky you have such a large tank it will help keep aggression much lower in general.
