Ok i been going threw this phaze where i have been looking for the right fish, i just got some Dovii, and they both are realy big panzies the both of them do nothing but hide up behind the filter, i am just looking for an aggresive fish i want something that will try to attack me even when i walk by his tank......... or try to get me threw the tank....... something that will actually chase me hand...... something that will try and take me arm off when i stick it in the tank........ by the way this fish will be lonner, all by himself in a tank.......... anyone have any ideas?
