My sister helped me acclimate some corals and add a few fish and inverts to my tank. She absolutely wants to set up a tank herself (she had a 55g freshwater for a long time that she loved). She is, however, "animal'd out" right now, as she has two dogs (the third passed on Monday), two cats, a guinea pig, and a bearded dragon.
I've got an upgrade coming Monday, and there's a good chance she's going to inherit some of my stuff, which just might kick-start her into the hobby even while she currently hosts a small zoo. Haha.
Otherwise, though, I have very little real-world influence. I mostly keep to myself.
