CATDOLL : CATDOLL: Which small tropical fish can be raised together and look good together?

Guppy, red light fish, red swordfish, black Mary. A few of these will make your fish tank full. These are relatively easy to keep tropical fish.

The following are the key points you must keep in mind to raise tropical ornamental fish, for your reference.

1 To keep good fish, you must first learn to buy good fish: healthy fish swim in the middle and lower layers of the water body (except for the upper layer fish), compete for food, swim naturally and leisurely, have clear and transparent tail fins, and clear eyes, and are large. Fish that sink to the bottom, float to the top, swim in a struggling state, have external injuries, white hair, white spots, thick and turbid tail fins, severe bloodshot, dark body color, turbid eyes, stay alone, refuse to eat, or rub the tank with their bodies are all sick fish and must not be purchased.

2 If you plan to raise several different species of fish in the same tank, you must take into account the compatibility between the different species of fish. Fierce fish and gentle fish cannot be raised together; fish with too many individual differences cannot be raised together (gentle fish species can be considered); fish with different water quality requirements cannot be raised together, etc.

3 When buying, for aggressive and large and medium-sized fish, not only should they be inflated to retain oxygen, but they should also be covered with a black bag to reduce external interference with the fish. High-end fish should be packed in separate bags to prevent them from touching each other and causing damage. When buying fish in winter, you should also pay attention to heat preservation. The plastic bag for the fish must be thick and reliable, especially for those fish with hard fins.

4. Don't rush to put tropical fish into the tank after you bring them home. You should first immerse the plastic bag containing the fish into the fish tank for ten to twenty minutes before opening it, so that the water in the tank can flow back into the bag several times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality. If there is light, turn it off. Fish are quieter in the dark and are not easily frightened.

5. Tropical fish are best suited to living in a temperature range of 24℃-28℃, and can live normally in summer at 32℃. However, if the temperature suddenly changes too much, tropical fish cannot adapt. Therefore, before buying fish, you should not only adjust the water temperature of your own aquarium, but also pay attention to the water temperature of the aquarium store and your fish tank. The deviation should not be too large, generally within 4℃. If the water temperature deviation is too large, it is better not to buy it temporarily, but also to make an extra trip to adjust the water temperature to basically the same before buying.

6. Do not change too much water in the fish tank at one time, as this will cause water quality discomfort. Water quality includes pH value, hardness, chloride ions, dissolved oxygen, nitrates, sulfides, proteins and turbidity. Tropical fish have adapted to living in the original water quality. If all the water is changed, the water quality will suddenly change, and they will not be able to adapt, causing their physical fitness to deteriorate and become sick. If you need to rinse the bottom of the tank, you should also keep most of the old water. After washing the tank, return the remaining water to the tank and add new water.

7 Pay attention to the density of fish. Tropical fish like a large space for activities. Beginners often buy the fish they like, and rarely consider how many fish can be kept in the tank. This point requires special attention. Usually, 1 liter of water should be used to raise 1 cm long fish. If your fish tank holds 100 liters of water, it is safe to feed at most 10 tropical fish of 10 cm long. I personally insist on controlling the target of about 1.5 liters. In a larger space, fish are more active, strong, and colorful. Raising too many fish, too high a density, lack of oxygen in the water, and deterioration of water quality are the main causes of tropical fish illness and death.

8 How to feed. The most important thing to pay attention to in an ornamental fish tank is to control the feeding, once or twice a day, and it is best to finish eating within 3 to 5 minutes. Feed less on rainy days and do not feed at night. Fish need to consume more oxygen in the process of digesting food. On rainy days and at night, the air pressure is lower, and the dissolved oxygen in the water is also low. Feeding fish at this time may cause severe hypoxia in the water and cause fish death. Most fish deaths occur at night, and severe hypoxia in the water is one of the main reasons.

9 The bait must be clean. This is the most easily overlooked by beginners. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy branded frozen fresh food produced by professional companies, such as bloodworms, brine shrimp, etc. Although live worms such as water earthworms and water red worms are the favorite of tropical fish, live worms grow in polluted water environments and are very easy to die and rot during temporary breeding. Therefore, be cautious when feeding live food.

10 Keep the water clean. After eating, tropical fish consume a lot of oxygen and excrete a lot of waste, which pollutes the water and breeds bacteria. In order to keep the water clean, a high-efficiency filter must be installed. If you raise fish in a bare tank, you must replace one-tenth or slightly more of the old water every day while removing the precipitate from the bottom of the tank. This must not be neglected, especially in summer. For an ecological tank where fish and aquatic plants are raised together, it is sufficient to replace 1/3 to 1/4 of the water once a week. The filter can be designed with an aeration system, so that filtering and aeration can be carried out at the same time, which not only purifies the water but also replenishes oxygen. However, aquariums with aquatic plants should not be aerated.

11 Do not bring grease and detergent into the water. Grease will float on the water surface and isolate the air, so that the oxygen in the water cannot be replenished, which will cause tropical fish to die of lack of oxygen. Feeding meat or even using hand cream on your hands will bring grease into the water, which should be carefully avoided. Therefore, the fish tank should be kept away from places where oil and gas are generated.

12 It is best to start with cheap and easy-to-raise fish. Once you have accumulated experience, you can then raise valuable species. This will help you become more proficient and successful.

Guppy, red light fish, red swordfish, black Mary. A few of these will make your fish tank pretty much complete. These are relatively easy-to-raise tropical fish.

Fish such as scavenger fish, zebra fish, discus fish, angel fish, skirt carp, Mary, etc. can be mixed. You can put sand and water plants in the tank, pay attention to the water temperature, do not feed too much, and pay attention to the light.

Make a grass tank, lay some bottom sand, get some well-shaped driftwood, plant some aquatic plants, and then I recommend you choose small fish, such as red-nosed scissors, peacock, cardinal lantern, red and green lights, black Mary, and get a few cod fish, which can eat moss and are cuter than scavengers.

Small ones are fine, peacock, traffic light, zebra, lemon light.
