While generally considered shy and nocturnal, what specific aspect of their environment are Zebra Plecos moderately territorial about in groups?
Answer
Their chosen hiding spaces or caves.
Although the Zebra Pleco exhibits shy behavior and spends much of the day resting hidden, they are not entirely passive when it comes to resource defense. They possess a moderate level of territoriality, which is primarily focused on establishing and defending secure, dark hiding spots or caves. For this reason, when keeping groups of these catfish, it is essential that the tank is adequately sized and provisioned with numerous refuges, ensuring every individual has a private territory claim to prevent chronic stress from feeling exposed.
