Male purple seal fish
Female purple-printed fish
Among the many pseudo-bass species, the purple seal can be described as the most famous variety. They may also be the largest species in the genus, with adult males growing up to 20 cm. Purple marks are found in the Philippines, Australia, southern Japan, and the Waters of the Malay Archipelago, and there are slight differences in morphology between species in various regions. Males are generally pink or orange-red with a purple patch in the middle of their body. Females are yellow or pink, have no purple patches on their bodies, and are 5–8 cm smaller than males. Therefore, many beginners think that they are basically two different fish.
Purple seals usually move in groups in nature, with a community dominated by 1–3 males, followed by dozens of females. Therefore, there are many more females than males. Because it is a social animal, it is difficult to raise only one in an artificial environment, and it is best to raise it in groups in the proportion of one male and 5 females. Two male purple seals are kept in an aquarium, and sometimes fight and even lead to mutual killing. Unless the aquarium is large, it is not recommended to raise multiple males.
Purple seals are very difficult to keep ornamental fish, they are timid, picky and nervous. Newly introduced individuals into the aquarium are prone to bumping around and ending up bleeding from their heads and dying. To avoid this, keep a dark environment for several hours after turning the water and putting it in. Purple Seal is difficult to accept artificial feed, even if it is fresh shrimp meat, it takes a period of discipline to accept. Males over 18 cm are less likely to open their mouths to eat in an artificial environment. Sometimes, the breeding purple seal will suddenly crash around in complete health and eventually die. This is related to the fact that the living environment is too small, they need a large aquarium to release the pressure caused by captivity, I think at least 800 liters of water, otherwise there will be "convulsions" events.
