I have a 55 gallon tank with 4 Zerbra danios, 3 loaches, and 2 guppies. I'm also going to get a bristlenose plecos. I know the schools aren't big enough currently so I'm going to fill the schools up. I also know that the water can't be a perfect temperature for every fish, but I keep my temperature at 75 F. I'm wondering if I'm asking for trouble if I get a betta fish. I feel like the danios will nip the betta's fin. Do you think this will be a problem? If I get around 10 danios would that help minimize them picking on the betta?
