So at what size do Red Terrors get earn their name? I've got two in a small growout tank with a RTM. Obviously they will need a bigger tank eventually here seeing as their only 2 inches atm. And the RTM is 3. But my question is, will they need to be separated at some point? They are complety fine atm, the RTM is the king of the tank for sure. I belive its a male and female RT and a female RTM. (These are purely guesses at this size. ) has anyone had any luck keeping these two together? The grow out tank is 46g, I'm getting rid of my 90 and getting a 125. I plan on putting them in that untill they out grow it. I know that the RT's will eventually need closer to a 180+ and I fully plan of getting one. Just need time.
