CATDOLL : CATDOLL: How do tropical fish farms heat the fish ponds?

You can use a coal-burning stove to raise the indoor temperature, which is what most fish shops do. Then thicken the roof and walls with honeycomb plastic panels to keep them warm.

For ventilation and smoke exhaust, you need to build pipes. Old-fashioned iron pipes are fine. They don't need to be too expensive. Generally, coal stoves and ventilation and smoke exhaust pipes are sold together. The total cost depends on the length of the iron pipes you use to lay the pipes. It won't be too expensive, but you usually have to maintain the indoor temperature at 25~26 degrees Celsius. In particular, dragon fish and pig-nosed turtles have more stringent temperature requirements. If you only raise some fish like red parrots, maps, carp, and carp, you don't need a high temperature. 20~25 degrees Celsius is enough.

Tropical fish life habits:

The water temperature for tropical fish is generally controlled between 24 and 28 degrees Celsius.

Within this temperature range, tropical fish have a strong appetite.

It thrives and grows rapidly. It is not affected by external temperature changes and always maintains a relatively stable state. Tropical fish food includes fish worms, water worms, earthworms, mealworms, small live fish, pellet feed, etc.

There are many species of tropical fish, and their sizes vary greatly, so the choice of bait for different species of tropical fish is also different.

Different. For tropical fish with a body length of 3 to 12 cm, the main bait is turtle worms, supplemented by brine shrimp (i.e., artemia), water earthworms, bloodworms, and mealworms. For tropical fish with a body length of more than 12 cm, turtle worms are small and have poor palatability, so slightly larger baits should be selected, mainly bloodworms, water earthworms, mealworms, small live fish, etc. Most tropical fish are mainly fed with animal baits, and small species can also be domesticated to feed mainly with granular feeds, while there are very few fish that are mainly fed with plant baits.
