Opaline Gourami (Trichogaster trichopterus)

The Opaline Gourami or Trichogaster trichopterus is a popular aquarium fish that has a silver coloration with dark blue markings. Also known as the Marbled Gourami, Three Spot Gourami, Blue gourami, Cosby gourami, Gold gourami, Golden gourami this type of Gourami is small, growing to only about 6" and is considered to be quite peaceful. From what I understand the Opaline Gourami is one of the most interesting fish to watch grow up. Have a look at this video to see the baby fry in action...

Like a few other species of fish the Opaline Gourami breathes real air. This defines them as a Labyrinth Fish and means that you need to allow access to the surface of your tank in order for this fish to survive.

These fish require a tank of at least 30 gallons and are considered to be quite compatible with a lot of different tank mates of similar size and aggressiveness. As with most fish providing a lot of hiding spaces is crucial to keeping your fish happy.
The Male Opaline Gourami will build a bubble nest and then has a bizarre mating ritual in which the fish will dance in front of the female, flaring its fins and raising up its tail. This means that mating is imminent and if you want to encourage the process even more you should reduce your water level. After spawning the male can become aggressive toward the female Opaline Gourami so watch out. Sometimes separating them is the best idea. Make sure to change the water often after the fry have hatched.

The fry of this species can be fed infusoria and nauplii while the adult versions should be fed flake food and meaty food including bloodworms and brine shrimp. Water conditions for this freshwater aquarium fish should be 72-82° F with a PH Level of 6.0-8.0.
