I added a green bubble tip about a month ago for my male and female SI percs. Neither of them showed any interest until tonight. The female has finally taken up with the anemone and is going nuts with it. The male is still hanging out in the corner, though (lights are out). Hopefully he'll be lured into it by the female today when the lights go on. I was starting to think they would never hook up with the gbta but it only took a month.
