Just picked up a used tank today I found off craigslist. It's a 2.5 gallon with LED light, a Red Sea nano filter, black gravel, ornament and plant - everything works - for $20

I cleaned it with hot water, scrubbed out the old algae, and added new decholorinated water, and I'm super-cycling the tank right now with a filter from my other 10 gallon tank.
For my 10g heated tank I do 10% water changes once a week and change the filter about once a month and my water is stable, clear and fish are happy. For my new 2.5g will I need to do anything differently?
Thanks. I'm going betta shopping tomorrow. Couldn't find any today that were up to my standards
