I have a RES Myrtle, that is 18 months old, we brought home another who we named Tiger 2, we have kept them seperate for 6 months now.
The reason for that is we had brought home another RES and put it in with Myrlte when it was only 2 months old and we came home from work to find that Myrtle had bitten it's head and it ofcourse died
We put Tiger 2 in with her today while cleaning it's tank and also to see how Myrtle would react while we were here to supervise. Myrtle ignored Tiger 2 for a while but than when she finally went to check Tiger 2 out she started snapping at Tiger 2's back legs, Of course we took Tiger 2 out.
My question is, when and how is the best time to put them together, should we wait till Tiger 2 is a year old and the same size as Myrtle
