Coming from an RA, we don't like to, but we kinda have to enforce policy. Certain things take precedence, but we try to treat everything equally. I will say if you had tanks, your RA saw them, as most colleges do 3-5 dorm checks a year.
For my school and many others, fish are more than encouraged! We have a lot of bio students who catch, observe and release from the river next to our school.
A note on roommates-- be very cautious. Unless you become an RA and live alone, or just put up the money, most roommates like to fiddle with your tanks and pets at some point. Look for "They looked hungry don't be mad bro," if you don't lay out rules first like already stated lol.
