1. What are the signs of stress in fish？
|Symptoms:You should observe your fish often for any of these signs of stress.|
|Gasping at the Surface:|
Gasping at the Surface:If a fish is gasping his mouth at the surface, this is a sign of stress brought on by poor water conditions, usually a lack of oxygen.
Ich, characterized by white spots on the body of a fish, and other diseases can appear as a result of your stress. If you observe this or any other visible ailments or sores on your fish, you should talk to your veterinarian about possible treatments.
When fish are stressed, they often develop odd swimming patterns. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress. Talk to your veterinarian about treatment and look into what may be causing the stress and alleviating it.
2.What causes fish stress？
Improper water conditions: The conditions of your fish’s water can cause lots of stress if they are poorly maintained. If you see your fish gasping at the surface, you should conduct a water test immediately to find out if there is anything wrong with it. High ammonia or nitrate levels, low oxygen levels, improper temperature or a high or low pH can cause stress. If you have a saltwater tank, incorrect salt levels could have a similar effect.
Troubles with other fish: Like humans, not all fish get along, and they often feel cramped if they live with too many other fish or the wrong fish. Make sure you don’t put too many fish in your aquarium, as this leads to various problems in fish combativeness and water quality. Also, fish need multiple hiding spots so that they can avoid aggressors. In addition, when feeding your fish, try to evenly distribute the food, so fish don’t have to compete.
Other factors: In addition to those already mentioned, there are some other factors that lead to stress. One of these is the presence of any added chemicals or medications in the fish’s tank. Make sure when treating a sick fish, he is properly quarantined first. Additionally, improper diet can cause stress. Make sure you know your fish’s ideal diet and do your best to adhere to it. Finally, disturbances of a fish’s habitat such as banging or loud noises can lead to stress. If you have children, make sure they know to respect the fish’s home.

4.How to determine the betta fish is female or male?
|Colors||Often males are more vividly colored than females; however, color alone is not a definitive predictor of gender. Males generally display more vibrant colors than females, but females can be quite colorful, too.|
|Vertical Stripes||Female betta will display vertical stripes on their body when they are ready to mate, while males do not.|
|Body Shape||Generally, females are a bit shorter and more wide-bodied than male betta. Males tend to have more elongated bodies that are slightly flatter, side-to-side.|
|Fins||Male betta have much longer fins, sometimes as much as three or four times the length of the females' fins. While some varieties of betta have males sporting short caudal (tail) fins, in most varieties the females have shorter caudal fins and the males have longer fins. The ventral fins of the male are noticeably longer and thicker than those of the female.|
|Egg Spot||Mature females display an “egg spot” between the ventral and anal fins. This is actually the ovipositor, which is used to lay the eggs. Males rarely show an egg spot.|
|Beard||Bettas have a membrane beneath the gill plate cover called the opercular membrane. This membrane appears as a “beard” and is displayed when the fish flares its gill plates. Males have a much larger beard, so large that often it is visible even when the male is not flaring. Females also have a beard, but it is much smaller and not visible when the female isn’t flaring.|
|Male and Female Flaring||When bettas flare, the differences between the sexes become more apparent. Males display a large beard, while females have a much smaller, less pronounced beard. Females may also assume a head-down posture when flaring, a posture that males do not exhibit.|
|Aggression||Female bettas aren't nearly the fighters that males are, but they can be aggressive toward one another and to other fish. Aggression between females can be very stressful, especially if there are only two females and one tends to bully the other. For this reason, it is recommended that if you are keeping more than one, you should keep at least five females in the same aquarium so that aggressive behavior is more diffused and not directed toward the same individual.|
|Bubble Nests||Generally, only male bettas blow a bubble nest. This is a nest made of saliva bubbles that the fish creates on the surface of the water to protect the eggs during breeding.1 Again this is not absolute, as occasionally a female will blow a bubble nest. However, those instances are fairly rare. Males create bubble nests in preparation for breeding with a female and will make nests, even if they have no mate in the tank.|
