Blue gourami

The pink kissing gourami, scientifically known as Helostoma temminckii, is a freshwater fish native to Southeast Asia. They are known for their unique "kissing" behavior, where they press their lips together, often in territorial displays between males, though it's not an actual act of affection. These fish are generally peaceful and can grow to be quite large, up to 12 inches (30 cm) in captivity. They have a lifespan of about 5-8 years.

The "natural fish" is brown with faint bars and two dark spots on each side that, along with the eyes, give this fish one of its common names, the Threespot Gourami. The Opaline Gourami has a silvery-blue body with darker markings. The markings often have a bluish tint to them.

The Pearl Gourami, also known as the Leeri Gourami or Lace Gourami (Trichopodus leerii), is a freshwater fish known for its peaceful nature and striking appearance. It has a silvery body with tiny white "pearl" like spots and a prominent horizontal black stripe. Males are more colorful, developing an orange or red throat area, and have longer, more pointed fins, especially the dorsal fin.

Red Honey Dwarf Gourami (Trichogaster chuna) are small, peaceful, and vibrant freshwater fish, known for their striking red or orange coloration, especially in males. They are relatively small, reaching about 2 inches in length, and are a good choice for community tanks with other peaceful, similarly sized fish. These fish are also known as Honey Gouramis or Dwarf Honey Gouramis.
