No don't post on your moms facebook! Not a good idea. Try and show her the difference between your fishes. I notice that when they are in cold and dirty water they are paler, and their fins are clamped. Try and point out the difference. Honestly if you keep up with water changes there is nothing wrong with a 1 gallon. Just ask if you can get them heaters and do the maintenance.
If you post on facebook it will seem like you are disrespecting her. So I would suggest not doing that!
