Tank-Raised Sailfin Corydoras

Sailfin corys grow noticeably larger and stockier than most of their relatives, and true to the name, the dorsal fin sits taller and more sail-like on adults — likely a display feature during spawning behavior, when Corydoras form the classic 'T-position' where a female presses her mouth to a male's flank to trigger fertilization while cupping eggs in her pelvic fins.
