Which category of fish should be avoided due to the nocturnal activity of Pictus Catfish potentially causing stress?
Answer
Slow-moving or docile species like Discus or Gourami
Selection of compatible tankmates requires consideration of activity levels, particularly concerning the Pictus Catfish's behavior after the lights go out. Slow-moving or docile species, such as Discus or Gourami, are strongly discouraged as companions. The swift, nocturnal activity and potential foraging excitement of the Pictus Catfish can easily stress these calmer inhabitants, disrupting their routine and well-being. In contrast, fish that are large and fast, preferring the mid to upper water columns, generally coexist better by minimizing direct competition or interaction at the substrate level.
