Our daughter’s townhouse roommates found a fish tank and so they decided they wanted to keep a fish because they wanted see the water and to watch the fish swim.
No one volunteered to care or pay for fish food, filters, upkeep and what to do on breaks. So one of them got a plastic fish leftover from a Luau, stuck it in the tank and they named him Fred (Flintstones which they had to look up on the internet). Everyone who entered daily said “Hello” to Fred. They were supposed to find a companion Barney for Fred but no one ever brought in a Barney.
Wait until you get to the dorm and aren’t fighting over cleaning the tank, getting food, checking to see who fed him last, changing the room deodorizers, and arguing over what happens over the breaks.
You will be busy enough trying to do laundry, getting your meals, studying, submitting your papers, getting to class on time, going to the labs, meeting your professors’ office hours, and replenishing your toiletries, clothes, and supplies. College coursework will be tougher than you think. You may get C’s, D’s and F’s the first quarter/semester. It goes by really rapidly and your assigned readings will be longer and more difficult. You wont have a lot of time for you, let alone a pet.
