1, indoor aquarium should avoid long-term direct sunlight, otherwise, hairy blue-green or blue-black epiphytic algae will breed on the stems and leaves of aquatic plants, the walls and bottom materials of the aquarium, making a box of fish dull and even dirty. In order to avoid this unpleasant phenomenon, curtains should be drawn on sunny days, or the sunlight directed at the aquarium should be blocked with green transparent paper. Generally speaking, there are not many algae in clean fish tanks and fish tanks with few fish.
2. The water temperature of tropical fish is generally 20~30℃. However, different kinds of tropical fish have different requirements for water temperature. For example, guppies, swordfish, black Mary and other fish species can tolerate the water temperature around 18℃ without dying, while swallowtail and tiger fish will die when the water temperature is lower than 18℃. Most tropical fish are very sensitive to water temperature. If the water temperature changes by 2℃, they will catch a cold. If the water temperature fluctuates for a long time, fish will suffer from various diseases. So try to keep the water temperature constant.
3. The lighting equipment of tropical fish is mainly fluorescent lamps, in addition to halogen lamps and mercury lamps. For the lighting of a single aquarium, sometimes underwater colored lights can also be used. It is a small glass tube, which can be directly placed under water and adsorbed on the glass tube wall. Its lamp tube can emit red, blue, green, white and other different colors, and the beautification effect is good.
4. The bait of tropical fish includes fish worms, earthworms, earthworms, Tenebrio molitor, small live fish, pellet feed, etc. There are many kinds of tropical fish, and their sizes vary greatly, so different kinds of tropical fish have different bait choices. Tropical fish mainly feed on animals, and small species can also be domesticated as pellet feed, while a few fish feed on plants.
5. The feeding amount of tropical fish should be decided according to the size and quantity of fish. Generally, domestic cultured tropical fish only need to be fed 1-2 times a day, and the feeding amount should be eaten within 5- 10 minutes. When raising tropical fish in large quantities, feed them 2-3 times a day.
6. Changing water is the simplest and most effective way to change water quality, but the workload of changing water is large, especially when the aquarium is small and scenic, the process is complicated and cumbersome. Before changing the water, cut off the power supply of all the electrical appliances in the aquarium, take out all the fish and scenery, and drain the water. After the aquarium is cleaned, put away all the scenery and put it in fresh water for later use.
