Habitat – Tropical Fish For Sale

Tropical fish are used to warmer water temperatures. Therefore, a water heater must be purchased to keep temperatures above 25 degrees. The water must be clean at all times, so a filter must be installed according to the size of the fish tank. The filter has to be of high quality since the life of the fish depends on it. Poorly clean water can cause fish diseases and lead to death.

Tropical ecosystems are made up of plants, gravel, and some objects that serve as their hiding places. To fully recreate its natural ecosystem, the tank will need to be decorated so that the fish can move and hide.

Before placing the pieces in the aquarium, they should be washed with running water to eliminate possible impurities that contaminate the aquarium and facilitate the spread of diseases.

As for the diet, this is already somewhat more complex, since it depends entirely on the type of diet that each species has. Although the fish are tropical, each one has a special diet. Some of them are carnivores, others herbivores, others are more versatile and eat everything.
