Hi @Anemone Can you shed some light on the whole rumour that you cant keep RBTA's and GBTA's in the same tank? I have read and heard mixed stories with regard to keeping them together, I have seen pics of tanks with both colours in the same tank and everthing is fine and yet I have heard stories of chemical warfare between the two if kept in the same tank and its usually always the RBTA that lands up dying. A local reefer I know used to breed both species for years and had more than 20 of each colour at one point, until one day he placed a GBTA in the tank with his RBTA's and he landed up loosing all but one of the RBTA's. Are there factors that would cause the two to fight if the stories are true in some circumstances? Reason I ask this is I have had a RBTA for a long time now and brought it back from the size and colour of a golf ball to a BIG bright red beauty and am thinking of adding a GBTA that my friend is selling, to my tank...after all the RBTA has been through I would hate to kill it by adding the GBTA is the stories are true.
