Meet my new Sorority tank. 3 are quite a bit older and bigger than the 3 dumbos I have! My male Betta is in a tank next to them and he really doesn't like them! Everytime I take down the divider he really gives them a good flare, he's normally quite chilled with all his other tank mates etc so its quite strange to see him so aggressive. The girls are currently in with a few Corydoras' and a snail or 2.
