Yikes...she seems lonely tho. Someone mentioned a guppy, and someone else said a molly, but do you folks have any suggestions? And I was thinking I should get a plant? All input will be considered...thanks!
I would recommend only having the 1 Betta that you already have in tank.
Due to Betta being quite territorial, any other fishes that would be considered encrouching it's territory/area would be killed, or chased/stressed till it also dies. Guppies/Molies/Platies are all pretty/colourful and middle/high dwellers that the Betta might consider as a threat. Some people has had success but with tanks that have loads of hide out for the other fishes.
Cory cats are considered as bottom dwellers and they would predominantly just swim about the bottom fuffing about. The Betta don't really consider this area as their territory and would leave the cory cats alone.
So my suggestion would be the one Betta plus 4-6 Cory cats (they to have the tendency to favour life in groups).
Planted tanks would be a good idea if you can manage the maintenance. If not maintained well, they will just add more bio load to your aquarium.
Btw, I'm also looking to have my 2nd aquarium with a Betta and Corys..
