Good choice. My GSM pair have been laying eggs since December, and still haven't got aggressive with me or other fish. They have 3 BTA's , but are model citizens. My other female(which is going to a new home this coming weekend), would not leave me alone. Never drew blood, and lived happily with a Occy, but was brutal to me, is getting replaced with a group of Occys. Your GSM's should be hosted JUMP, by the BTA. Your gonna love them.
