Tracy yeah I noticed that... My friend's blind betta sulks in a bigger tank. He likes his 1.5 gallons... I don't. But, better than him sulking and not doing anything. We got him a mini heater, and he is pretty good.
Like I said personally I have had and do have bowls (2 gallon so-called goldfish bowls), but I have tanks too. Plus I like to add stuff, and make it interesting for the fishies :p and I spoil them... XD if I had room, I want to get one of those pond things and get some girlies, live plants, etc :) because it's ascetically pleasing.
However I have seen betta fish in shoe heels, and necklace pendants (from this site) and I do strongly disagree with something like that.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
