I removed a rock that had my sm. rbta and 10 majanos and placed it in a large tupperware bowl with tank water in it. With a hypordermic needle I injected all 10 Maj.s with red wine vinegar. I used red so I could see it in the water. If u miss then u can see the red vinegar squiting out the sides. The small ones were injected directly in the center/mouth, same w/larger ones and also in the sides. I let em sit/soak for 1 hour and then plucked them from the rock/ their holes with a pair of tweezers. They came right off in 1 piece. I also injected a majano that had crawled into the center of a cluster of stair polyps. He plucked off in one piece too. I hope this ends my Majano problem. Will keep u posted.
