wow thanks for all that info!
as of right now, I have no filter.
The guy at the store said it wasn't mandatory for a betta but said to come back if I decided to make that leap.
The people at Petsmart/Petco said that they very very rarely get 5 gallon glass tanks in.
Luckily, I found a local fish store that had them - $15! perfect!
but i had to get the top separately. I dont remember how much I paid for the top.
Ted seems to be pretty happy in his new setup. All I need is more plants and maybe one more hiding spot.
Now my next question is:
How often do I change his water? and do I change all of it? or just some of it?
