We've had a gbta for quite a few months now. About 2 months ago, we added in a pair of gsm. After acclimating, it took the male about 5min. to find the gbta and then they both moved in to host. They are always in the gbta, nestling it, bring it food, etc. About 3 weeks ago, we added in a blue-tipped sebae. After the first few days the sebae was in the tank, we noticed the female gsm was going over to visit. She'll swim to the sebae, nestle inside it and stay for a minute or 2, then she swims back over to the gbta. The male hasn't shown any interest in the sebae. The female visits the sebae about 4-5x a day from our observations. Is this common behavior? Does she want, as our LFS suspects, to hose the sebae instead of the gbta and is waiting for the male to join her there?
