Thanks for the advice so far. The larger tank was definitely winning in my mind whenever I thought about the future and whether I would want to upgrade or it. It just kept seeming easier to start with the larger tank.
I am currently looking into getting my first aquarium and I need some advice on tank size. The LFS near me is having a holiday sale and there are two tanks that would work in the space I have. They both come with:
light
heater
filter
net
water conditioner
food
thermometer
reminder thingy
stand...
