AITA for refusing to house my daughter's neglected Lizard in my house

As a child I had a phobia of snakes. I would wake up experiencing night terrors and would see snakes in the folds of blankets, curtains, laundry and even along the baseboards. A snake on TV was guaranteed to bring about a nightmare. It took a lot of work & prayer but I moved passed the phobia. I dislike all reptiles. A Lizard is just a snake with legs. My daughter decided she wanted a Lizard and I established a hard boundary. I let it be known the Lizard would never live with us. She is 16 now and the Lizard has lived at her grandma's house. My sister and the friend that gifted her the Lizard made arrangements for the lizard's living situation. My sister recently got a boyfriend and has basically been living with him instead of mom's house. My mom who is 70 we will call Grandma calls and tells me my sister May hasn't been around so the Lizard wasn't fed or watered for 2 weeks. I was then told the Lizard has to come to my house because it is being neglected. I of course said no. My daughter is trying to lecture me about overcoming my fears. I believe you can move past a fear but not necessarily decide to embrace what you were once afraid of. I suggested the Lizard go to a new home or she drop by after school to care for it. I don't know why she got a Lizard. I think they thought they would be able to bully me into accepting their master plan. AITA for not letting a Lizard live with me when reptiles creep me out?
