HI Ok guys, I really want a Betta fish, what if I change out my entire stock, would I need to clean out the whole tank and cycle it again? I don't have any diseases at the moment, and my numbers are perfect. So how would I go about doing that? I can't just totally take out all the fish and then put in a Betta right? That would cause a mess in the cycle. Please Help! also, I wouldn't plan to clean out my whole stock, I would add other things in, like ghost shrimp and maybe a snail to balance the ammonia in the cycle. anyway, just an idea, how would you go about doing that? Thank you for reading my thread!
