I had two neon swordtails have fry bout the same time so i dont kno which fry belong to which sword. anyways most of the fry have the normalfan shaped tails, but a some of them comes to almost like aspear head like it doesnt fan. i have checked if the are just holding them closed and thats not it. so this spear shape is it a defect or just a normal mutation any help would be appreciated.
