Hi, I’m Lisa. This is my first time on a forum. If I don’t respond, it’s not intentional. I’m not totally sure how it works yet. I have a baby brachy. I never had a T of my own, but my father always liked them, so I bought one for him for Father’s Day one year (over 30 yrs ago). We loved it. My son gave me Vermillion, my brachy, about a year ago. She’s only about the size of a dime. Her nickname is Milli. She only has sand for a substrate, but I’m getting coco-fiber so I can change it. I know she’s tropical & needs more moisture.
