Yup, it sure is an image, and photobucket too. Does that mean not everyone can see my preachy-ness? Dangit!
Its basically a little picture condemning keeping bettas in uber-tiny tanks.
I belong more to the 5 gallon + crowd, but felt the need to post here noting that comparing tanks to rice paddies is comparing apples to oranges, because not only is the environment very different, but the fish themselves are. I think some heavily finned VT would absolutely fair poorly in a huge body of water, because thier fins are so heavy and cumbersome that they can hardly swim as it is. However, I don't see the argument of a plakat getting stressed out in a 10 gallon, because they are no poorer a swimmer than any other fish.
I'm a big believer of finding out what works best for your individual fish instead of lumping all bettas into "all bettas need 1 gallon" or "all bettas need 10 gallons," because different things stress out different animals. I just moved one of my bettas to a nice big tank, and all he does is "pace" all day now. His fins are getting ragged from swimming back and fourth endlessly, and his color is awful. I'm probably going to downgrade him, even though I don't want to, though I'm going to try planting more first. On the other hand, I have a betta who uses each and every inch of his 5 gallon, is miserable in anything smaller, and would probably like something bigger. When I move back out of my apartment, he's definately moving to a 10 gallon.
Also, there is so more more to proper betta care than tank size; they are the one species where tank size can vary quite dramatically without much of an ill effect to the fish. Behavioral enrichment, diet, temperature, pH, water cleanliness, etc. play a huge role in betta health, and really never seem to get as much consideration as tank size, which is a shame. While it is true that larger tanks tend to have a more stable temp and do not build up waste as quick, it is also entirely possible to have a large tank that is worse for the betta than a small one, due to something like poor husbandry, a stressfully fast current, or no environmental stimulation.
I could probably blab on and on about this, but I won't Hopefully this post helped to better clarify what I was getting at.
Ok. I'm done hijacking the thread, sorry for the outburst.
