I have a 10" male RTM and a 6.5" female RTM in a 180 gallon. They were purchased seperately and until Friday I had the female in a 100 gallon tank. I put her in the 180 gallon on Friday and the male has chased her pretty constantly since Friday. She's getting a bit tatered but still has lots of energy. I have a couple of questions, is there an adjustment period between male and female and this is what I'm witnessing, or do I need to get her out of the 180 gallon and give up the idea of trying to pair them up. Any advice would be greatly appreciated. Thanks.
