I got 3 beani's in a few weeks ago from Rapps..they were all in a 75g tank..these are the 3.5inch ones..they were getting along fine for bout a week then all of a sudden two were swimming around together while the other one was by himself most of the time. One day I got home and my wife told me that the one beani was getting attacked by the other two..i put a divider in that night and that weekend i seperated the other one into a 30g..now the odd thing is..the other two are still getting along and I havent seen any agression from them..could it be they are pairing up or are they still too young?..there are no tank mates at all..
