What a great start! Congrats on "surviving the cycle"

It can be very trying, expecially the first time. All your time spent researching paid off, well done.
A 29G is a good size for most homes. Give yourself some time before getting your next tank, tho.
You may have an opportunity to go even larger than that.
Also, after a few more months (give it 6 months to stablilize) your tank will be alot more mature and stable.
Then you can share filter media with you future tank (29G or bigger

) to get it's cycle going.
