【英语时差8,16】泰国斗鱼（上）

（单词翻译）

Siamese fighting fish are as beautiful and as brilliantly colorful as any other tropical fish, but this isn’t the reason they were first domesticated¹ by us humans. As their name implies, Siamese fighting fish can be rather pugnacious². Males will engage other males in violent and turbulent clashes that can involve severe fin³ nipping, or worse. We humans originally domesticated these fish not for their looks, but to stage contests between them. Apparently⁴, we like to see a good fight. Surprisingly, these fish also seem to enjoy watching a good fish fight, as scientists have discovered. When two Siamese fighting fish attack each other in a laboratory aquarium⁵, researchers noticed that the other males in the vicinity will stop to watch the fight very closely. Is this rubbernecking just idle curiosity? Apparently not.
