Charging Roommates Pet Rent for Unauthorized Fish Tank - A Fair Compromise or Overstepping Boundaries?
AITA for implementing 'pet rent' on roommates' unauthorized fish tank, sparking debate on respecting lease rules and fair compensation for increased costs?
A 28-year-old woman refused to let her roommates treat their lease like optional reading, and it turned into a full-on apartment standoff over a fish tank. One month after Sarah and Alex quietly hauled in a sizable setup for the living room, she realized the “no pets allowed” clause was being ignored in real time.
Here’s the messy part, they admitted they brought it in anyway because they figured it wouldn’t be a big deal. The OP tried to meet them halfway by proposing “pet rent,” basically charging them a monthly share for the extra water and electricity costs of running the tank, but Sarah and Alex weren’t buying it.
Now the whole apartment is tense, and she’s stuck wondering if enforcing the rules makes her the asshole.
Original Post
I (28F) live with two roommates, Sarah and Alex, in a small apartment. Our lease explicitly states no pets allowed.
About a month ago, I noticed Sarah and Alex had set up a sizable fish tank in our living room. I asked them about it, and they confessed they got it despite the rule because they thought it wouldn't be an issue.
I tried to be understanding, but it bothers me that they disregard our lease agreement. I came up with a compromise - 'pet rent.' I told them they could keep the tank, but each month they'd have to pay a share of what I calculated to be the increased water and electricity costs for running it.
Sarah and Alex were upset, saying it was unfair and that fish aren't 'real pets.' They argued they shouldn't have to pay more since the tank doesn't cause any damage. I countered that rules are rules, and they should respect them.
Things have been tense ever since. AITA for charging my roommates for 'pet rent' when they got an unauthorized fish tank?
The Pet Rent Dilemma
This situation really highlights the tension between personal freedom and shared living agreements. The OP’s roommates chose to set up a fish tank despite the lease’s strict prohibition on pets. It’s not just about the fish; it’s about the principle of respecting agreed-upon rules in a shared space. By implementing 'pet rent,' the OP is trying to navigate a tricky situation while holding her roommates accountable.
However, charging rent for a fish tank feels like a slippery slope. Could this lead to further charges for other ‘unauthorized’ items? The roommates might feel like they’re being penalized for adding a bit of life to their home, which complicates the negotiation even more.

After they confessed they thought the lease rule would not matter, she offered the compromise of “pet rent” based on her own math for water and electricity.
This also echoes the roommate who asked her partner to chip in for rent after cost-sharing arguments.

When Sarah and Alex pushed back by saying fish aren’t “real pets” and argued there’s no damage, the argument stopped being about costs and started being about respect for the lease.
A Lesson in Communication
The OP's decision to implement 'pet rent' might stem from frustration, but it also highlights a failure to address the issue directly with her roommates beforehand. If they had discussed the fish tank and its implications openly, they might have come to a more mutually agreeable solution.
This situation serves as a reminder that, in shared living arrangements, it’s crucial to express concerns and negotiate terms before resorting to penalties. After all, maintaining a harmonious living space often hinges on how well everyone can communicate about their needs and expectations.
