Thanks EvilVOG, I was not able to get stress coat today, they did not have it. I will switch to it as soon as I get some. Hopefully before the next water change.
Twilight Storm, thanks, he is a cutie isn't he. I will try to get some better photos of him in the next couple of days using my SLR instead of the phone camera. My house tends to be very dark so taking good photos can be challenging. I wish I had more windows!
The filter I ordered is the TOM Aquarium Mini Internal Filter 45gph adjustable flow from amazon:
I mostly liked the reviews from other Betta owners who say it works well in their tanks. It is made for small aquariums so I hope it is okay.
They also recommend a min heater with that: Elite Submersible Preset Heater Mini at http://www.amazon.com/Elite-Submersi...pr_product_top
It is the only small tank heater I found with an adjustable temp. Guage and it seems to get pretty good reviews.
Would anyone recomment a better heater or should I just order that one?
Thank you everyone for all your help, you are making me feel so much more competent.
