Mom wont let me keep my tank

My mom will not let me keep my betta tank in my room anymore she wants it completely gone its not harming anyone at all its only a small 20 gallon tank she thinks "it takes up to much room" and i need to "open up my room more" it barely takes up room and im not a overly big person i think the tank is just fine i want it to stay i want to stay in this hobby but she wants it completely gone. What can i do, what can i do? I want the tank to stay but she says its not up for discussion and wants it completely torn down and gone. I dont think she understands how much i love keeping fish and waking up to a betta staring at me it hardly takes up any room. What can i do to convince her to let me keep it if i dont get rid of it she said "ill take it and throw it into the trash myself" im scared i really like my fish tank i worked so hard on it to be a ecosystem.
