Note BE — Chapter XIII

"In the Magazine of Natural History" says Captain Brown, in one of his notes to White's Sellorne, "we have a curious account of the pugnacious propensities of these little animals. 'Having at various times,' says a correspondent, 'kept these little fish during the spring and part of the summer months, and paid close attention to their habits. I am enabled from my own experience to vouch for the facts I am about to relate. I have frequently kept them in a deal tub, about three feet two inches wide, and about two feet deep. When they are put in for some time, probably a day or two, they swim about in a shoal, apparently exploring their new habitation. Suddenly one will take possession of the tub, or, as it will sometimes happen, the bottom, and will instantly commence an attack upon his companions; and if any of them venture to oppose his sway, a regular and most furious battle ensues. They swim round and round each other with the greatest rapidity, biting, (their mouths being well furnished with teeth,) and endeavoring to pierce each other with their lateral spines, which, on this occasion, are projected. I have witnessed a battle of this sort which lasted several minutes before either would give way; and when one does submit, imagination can hardly conceive the vindictive fury of the conqueror, who, in the most persevering and unrelenting way, chases his rival from one part of the tub to another, until fairly exhausted with fatigue. From this period an interesting change takes place in the conqueror, who, from being a speckled and greenish-looking fish, assumes the most beautiful colors; the belly and lower jaws becoming a deep crimson, and the back sometimes a cream color, but generally a fine green, and the whole appearance full of animation and spirit. I have occasionally known three or four parts of the tub taken possession of by these little tyrants, who guard their territories with the strictest vigilance, and the slightest invasion brings on invariably a battle. A strange alteration immediately takes place in the defeated party: his gallant bearing forsakes him, his gay colors fade away, he becomes again speckled and ugly, and he hides his disgrace among his peaceable companions.'"
