What is the cause of the red swordfish's mouth rot?

Among all ovoviviparous ornamental fish, most of them are omnivorous and have the habit of gnawing on the tank wall and the leaves of aquatic plants, so they are very likely to get cottonmouth disease, and red swordfish is most likely to get this disease.

How to deal with red swordfish mouth rot

First, we can take out the sick fish, wrap it with a small wet towel, hold the fish body lightly with the left hand, pinch a little salt with the right finger, and apply it to the ulcer in the mouth of the sick fish. If there is white hair, you can use a small brush to gently brush off the white hair and then apply it. After pausing for two or three minutes, wash the sick fish's mouth in clean water, then apply erythromycin ointment or chlortetracycline ointment, and then throw the fish back into the tank.

What to do if the red swordfish has a rotten tail

Red swordfish are strong and generally do not get sick easily. If a red swordfish starts to have tail rot, you need to consider several recent aspects. First, has there been a sudden change in temperature recently, or whether the temperature has dropped suddenly? Secondly, there is no heating rod in the tank, and the fish cannot adapt to the temperature, resulting in a burnt tail. This type of tail will rot in a sawtooth shape, but it is relatively easy to solve. Just increase the temperature in the tank and then cut off the rotten tail.
