Neil bites his tail. This usually happens because he's been separated from his favorite girl, Chappy, or because he feels like it (yes, not a good reason, but for those of you with tail biters, you know how it is!) Anyway, his tail FINALLY grew back, and when I went to go say hi earlier, he looked like a crowntail. Aaaargh, it's so frustrating! His fins are so beautiful; they are orange, with dark orange dots, and dark blue and shiny turquoise rays. Sooooo beautiful! But anyways! I thought of a reason why he might do it-Chappy.
See, she's a crowntail, so what if he does it to make himself more attractive? Or, rather, to make his fins like hers?
It wouldn't be the first time anyone's altered their appearance to make themselves more appealing to the opposite sex, but....bettas too?
I guess it wouldn't be improbable, but it seems kinda silly. Have you guys noticed anything like this in your fish?
