Im not 100% Sure but apparntly there fins can get cut on them or something
but its up to you im no betta expert
see wht other peop;le say first aswel i kinda suck at betta care
Although i had 1 a couple weeks back who was fine and healthy When he died i was like NOOOO! =[ because i used to stroke mine ( yea he liked being stroked) and around a week later he died because of bloat or something ( i think i fed him too much blood worms my bad but hey! you learn from your mistakes right?)
