If Captive is terrestrial, avoid waterlogged conditions; if aquatic or semi-aquatic, maintain excellent filtration and regular water testing. In all cases, a mature, biologically stable setup is ideal, since invertebrates often struggle in “new” tanks with fluctuating parameters."}]}, {"type"=>"paragraph", "children"=>[{"type"=>"text", "value"=>"Diet and Feeding:"}]}, {"type"=>"paragraph", "children"=>[{"type"=>"text", "value"=>"Feed Captive according to its natural feeding type, but keep portions small and fresh.

If Captive is a scavenger or detritivore, provide frequent small feedings rather than large meals. If it is a predator, choose prey items no larger than the species can safely handle.

Captive specimens are typically adaptable swimmers that do best in a well-structured aquarium with ample open water for cruising plus sheltered areas and hiding spots to reduce stress. Temperament varies by species, but most captive-held fish are most manageable when housed in peaceful community settings, with conspecifics often showing either loose schooling behavior or mild territoriality depending on the group structure. A minimum tank size of 30 gallons is a practical baseline for smaller species, though larger or more active forms require substantially more room, and visual barriers created by rockwork, plants, or decor help break lines of sight and curb chasing. They generally coexist well with reef-safe species and other nonaggressive tank mates, provided tankmates are chosen for compatible size and temperament. Dietary habits are commonly omnivorous, with captive individuals readily accepting prepared foods, frozen fare, and natural grazing opportunities such as algae, small invertebrates, or other meaty items depending on the species.
