So I stopped at petco last night because I was bored. I should’ve known to stayed away from the betta section. I found a gorgeous mustard and blue male with almost his entire tail bitten off. I’ve been keeping fish off and on my whole life, but I’ve never tried to save one this bad. It actually kept me from sleeping last night. I just felt so bad for him. My question is if I go buy him, will his tail ever grow back in or is he a lost cause?
