yea they are in the same tank, at least for now they are, i had to take down the tank at home, due to a lazy brother, so i put them in my tank in my dorm room.  so far they are getting along fine.  i was thinking about putting up a smaller tank for the other two, but there just isnt that much room in these damn dorm rooms. lol.  i had to pull my desk 8 inches away from the wall, and make a custom stand for my 48 gallon that i have in here......   but thanks for all the advice everyone
