Alright so I have this 120g tank that is currently home to my senegal, del, and 2 ornates as well as a very lazy tiger oscar. All of the bichirs are around 6 to 6.5 inches and the oscar is about 7.5. I have a couple of clown loaches that are about 2.5 inches. Do you think theyd do alright in the big tank with everyone else or should I get the notion out of my mind?
