1, guppy
Peacock fish is not very demanding on water quality, and you can even try not to filter it. However, a simple oxygen-increasing device is needed. Don't feed frequently, it will worsen the water quality, make the fish sick, and lead to the death of these guppies.
2. Zebrafish
Zebrafish is also a kind of fish worthy of recommendation, because there are several dark blue stripes extending all the way to the caudal fin, much like zebras, so it has the name Zebrafish.
Zebrafish has strong resistance to the change of water temperature, as long as the water temperature is not lower than 20℃, it can survive, and the most suitable temperature is around 25℃, so it is friendly. It likes to travel in groups, and all kinds of animal bait or dry feed can be eaten.
3, tiger skin fish
Tiger skin fish is a tropical fish that likes high temperature and high oxygen, and its optimum growth temperature is 24-26℃. Tiger fish is omnivorous and gluttonous, but likes to eat live bait such as fish and worms, and likes to swim in the middle waters.
Step 4 fight fish
China betta males are fighting, but they can still be kept in groups. But if you want to cultivate expressive individuals, you'd better choose excellent young males to raise them alone.
Pay attention to adequate water, carefully filter the water and change the water regularly to keep the water clean. It is best to have dark bottom sand, a proper amount of plant mousse and floating aquatic plants, and the light should not be too strong. China betta can survive normally in low-oxygen water because its gills confuse organs.
Brief introduction of fish
Fish are mostly cold-blooded animals, and very few are warm-blooded animals. They breathe through their gills and have jaws and fins. The existing fish can be divided into two categories: cartilaginous fish and bony fish. Both groups of fish first appeared in the early Devonian. A more advanced group of linear finned fish, called bony fish, began to evolve in Jurassic and has become the most individualized fish.
