Wow that looks fantastic. I would love a look like this but i dont wanna bite your style :D
By all means. Imitation is the highest form of flattery.
I borrowed the terra cotta look from plenty before me, who I am sure borrowed it from others as well. The only original thing that came to me was putting plants in them, and giving them a look as though they fell out a window, etc.
I am still a little bit leery about them. I had to put much more gravel than I had previously planned, as one of my more beautiful bettas got stuck in the drain hole (a little bit of research on this matter would have resulted in this *not* happening), and was stuck there for a good hour, and suffered a terrible gash on top and bottom.
Be very careful with this look. Either take the entire bottom out of the terra cotta pot, or seal up the drain hole completely. I wish I did, and I am positive "Flo" does also.
