Sugar coating and nicely nicely? I don't think so
HOWEVER - some of the people in this thread have been very aggressive and critical. It doesn't matter how good the advice is, if people feel attacked and heavily criticised, they are less likely to take the advice. Be polite, be nice and give the advice in a caring way, rather than ranting about how awful some people are or how badly they keep their fish. A smile goes a long way, even online.
No one has been attacked, neither has anyone been agressive. The critiscism has been constructive , albeit blunt and useful advice given as to how the OP could improve the situation of his/her fish cheaply and quickly.
Loraxchick - It's less a question of happiness , as you quite rightly point out that this cannot be easily gauged in fish, but a question of good water quality that is easy and simple to manage which will result in healthy fish. Good water quality and ample swimming space is far more likely to give "happiness" such as it is in fish than in something smaller and harder to heat and filter ( as in find equipment for that is suitable ) which can suffer the effects of mistakes, poor management , or lack of/poor care for whatever reason, illness in the owner perhaps, or the owner going away and someone not experienced in the fishes care looking after the tank improperly despite instruction ect ( not remotely as unlikely or infrequent as it sounds sadly ), and most importantly, waste build up due to less water to dilute it.
There's simply no logical reason ( no not even supposed space issues, 14 inches can be found in even the smallest apartment ) for keeping pet bettas in tiny tanks, and unfiltered tanks also, since such setups are by their very small size harder to maintain as you yourself say, and pose more of a risk to the fishes health as the scope for things to go wrong ( as I stated above ) is far greater than in something much bigger, filtered and heated.
Going back to the OP, if he/she is indeed a kid, then one would presume that as a kid he/she has some sort of social life/activities and also probably homework ect to be getting on with. Having a larger easier to maintain tank is the only real logical soloution.
It may be a subject that comes up and goes in circles but it's a valid one and will continue to do so for as long as bettas are kept .
Garr.... It's not like I was allowed to get anything *else*, thoughs. T_T;
