Yeah, I noticed
this in the last catalog they sent me. 1 liter capacity, no filtration, "Requires minimal maintenance."QUOTE]
The description for this item begins, "A stress-minimizing bit of ambiance..." for the home, office, bedroom, kitchen, attic, tree-house etc. Fair enough. So how does it reduce stress? Well, you look at it and see the fish calmly floating around in the clean water, and you think about calm blue oceans and so on and your stress just melts away.... that is, of course, unless you never clean the water or try to maintain the bowl - then you're looking at a bowl of algae and fish poop. So then you say, "aha! i shall clean this water so it reminds me of calm blue oceans and so on!" so you clean it.. then you have to do it a few days later and you get tired of it. so you think, "hmm, i wish i could have a device that will FILTER the gunk out automatically... what would that FILTERING device be called...?" and you look in the trusty drsfostersmith catalog and find that it's called a .... filter! but alas, the filter doesnt hang on your little bowl, so you go out and buy a 5 or 10 gallon tank for your betta and wind up where you should have been from the start.
or alternative # 2: instead of seeing your betta calmly floating around, he lies on the bottom of the bowl with his fins tucked in... then you think about why he's doing that and realize that maybe he's not so comfortable in a little bowl. so you spend the 8 dollars on a ten gallon tank and there you have it! calm blue oceans....
ok, so i realize i probably just pissed off half of the betta owners out there

, but something just honestly bugs me about keeping a fish in a 1 LITER bowl - not even 1 gallon. think about it... would you fill up half of a coke bottle and keep a fish inside? that's what a liter is. compare that image in your mind to keeping one in a one GALLON bottle of water, or even putting 2 one gallon bottles together in a little 2 gallon tank.. it's a world of difference, i think...
