I have a 20 gallon tank with 4 zebra danios, 3 panda corys and 1 short-finned betta. Last night, we added a dwarf gourami. In the morning, the betta had his fins torn in 2 places and one of the danios has a big red wound on his gill. Should I get rid of the gourami or will he settle down with time? How should I treat the betta and the danio? Help!
