Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Nests side by side arranged in dense colonies near shore. Male digs nest and defends territory during prespawning period. Female approaches nesting colony when nest completed. Mating pairs swim in circles over nest, stop for short intervals to release sperm and egg. Male may chase mate away from nest, female may come back to same nest or move on to mate with another (Ref 4543). 北美洲: 東北方的墨西哥而且北至五大湖。 貿易在德國限制 (Anl。3 BArtSchV).
