So this is my tank set-up so far:
Tom Aquarium Mini Internal Filter (45gph)
Marina Betta Mini Heater (Temperature fluctuates between 76-80 degrees)
1 Double Tail Male Betta
It's been like this for about 3 months and I'm really interested in getting some live plants for the tank. I'm wondering, what kind of plants would be best, if I should change the substrate (to sand or soil?), do I need to re-cycle the tank if I change the substrate? I've heard that sand is easier to clean than gravel is, so I'm kinda interested in switching the substrate anyway.
I would appreciate any advice since I'm pretty new to this! Thanks!
