This is 10 months update. The fish are called Sparkling or Pygmy gourami.
Mixed shrimp tank isn’t really recommended. The babies will become wild shrimp color, clear and brownish.
The reason I did is b/c the gouramis will eat any new born shrimplets.
CRS are very sensitive to water parameters. I would only put them in a completely established tank. Probably over 3 months old tank, and temps below 26°C (79°F).
