one of my male convicts has a split in the middle of its tail all the way to the base, it was this way when i got it 3 months ago. the convict is 4-5" it is eating and growing but the tail will not grow in, so it's swimming with a double tail. i've seen videos on you tube (mostly arowanas) where they cut off a damaged tail to have it grow back right. now is this something i should do to fix its tail or just leave it because it is still competing in the tank.
