matt,
just before lights out, the Existing female was doing some serious chasing and did a good job of it. She got her spot back last night and all was well. today, she is being chased and has relegated to a corner of the tank. the new one is all over. When I first put them in, I had a Hawkfish that chased the little male to death and rather went after the female too. since then, she mainly hid around the pump return. it is good to see her about, but I sorta feel that first experience in the tank has effected her. that and I also think this new one may have already gone female. if this is the case, then I guess I will have to give up one before it is too late. we will just have to see...any advice is greatly appreciated.
