Why does Mary Fish attack its own kind and how to deal with it?

Excessive stocking density: Too much stocking density will limit the space for Mary fish to move in the water, leading to fighting between their own kind for space. A portion of the fish needs to be removed at this time and the injured fish treated. Not feeding for a long time: Not eating for a long time can make them irritable and aggressive. At this time, they need to be fed a small amount of food. Temperament is too fierce: This situation can add a glass plate in the fish tank to separate the fierce fish.

1. Excessive feeding density

1. Reason: When the feeding density is too high, the dissolved oxygen content in the water and the feeding food can not meet the needs of each fish. At this time, they will attack their own kind in order to compete for enough living space.

2. Treatment method: First of all, you can change a larger fish tank that can meet the needs of each Mary fish. If not, you can take out part of the fish in the fish tank to reduce the feeding density. Then a certain amount of yellow powder is smeared on the wounds of the injured fish to sterilize their wounds.

2. Do not feed

for a long time 1. Reason: Mary fish is a very hungry animal, but if they are not fed for a long time, they will feel hungry, and then they will attack their own kind.

2. Treatment: Put a small amount of live bait into the fish tank. Live bait is one of their favorite foods. But not too much, otherwise it will increase the burden on their intestines and stomach.

Three, the temperament is too ferocious

1, the reason: Mary fish is a kind of gentle fish, but also can not rule out the existence of ferocious fish. If the ferocious fish is kept with the gentle fish, the ferocious fish will attack the gentle fish.

2. How to deal with it: Use a glass plate to separate the ferocious Mary fish, so as to prevent the gentle fish from being bullied by the ferocious fish.
