Main types of tropical fish species suitable for a freshwater tropical fish aquarium.

Knowing the different types of tropical fish species when setting up a new aquarium or adding fish to your existing fish tank is important for the success of your home aquarium.

Freshwater tropical fish can range from very peaceful fish to very aggressive fish and everything in between. Something else to consider are the water parameters in which each individual type of fish is the most comfortable with.

Ideal Conditions for this Aquarium Fish

The Dwarf Gourami is another species from my tropical fish index. A few variants are available in Red, Blue and Neon Blue. The original has a light blue main body color with irregular red stripes running vertical over the body increasing towards the tail.

Appearance The dorsal and anal fins are very prominent in size in relation to body size. The pelvic fins are very distinct because of its thin long shape.

Peaceful, Community These are peaceful fish well suited to be placed with other smaller peaceful fish in a community aquarium setup.

Strata They are fairly calm and shy fish that will explore all areas of fish tanks but mainly stay in the top to middle regions.

Feeding In general they do well on flake food and blood worms supplemented with the occasional live food like brine shrimp.

Breeding them is reasonably easy provided that you take some extra care. Isolating a pair of Gouramis in their own tank, supplementing their food with live food like brine shrimp and increasing the temperature to 80.6°F or 27°C should trigger breeding.

The male will build a bubble nest in which the eggs will remain until they hatch after about a day. After the eggs are laid remove the female and after the fry have hatched remove the male.

Lifespan They can live for up to four years and beyond when they are kept in the most ideal conditions with regular water changes.
