Just got manzanita branches from PC1 (forum member). These are great. Affordable. Definitely going back for more.
Thanks for the concerns about the size of the tank regarding the discuses. Most likely, just one to two discuses the most. I will upgrade to a bigger tank soon. For now, just a 29 gallon. Made a typo on it being a 20 gallon on the first post.
I think the tank and stand look fabulous!
I think you should really consider different fish. Considering that a 29 doesn't really hold 29 gallons even, and discus are very sensitive fish, the wood and plants will just take up more swimming space. They won't be very happy, stressed fish are prone to illnesses. There are many smaller fish that are very attractive that would be great in a smaller tank, like apistogrammas.
