I don't know...you haven't given any information. How long are they going to be in the cup? a day, a week, a month? what are they observing? it all makes a difference.
at any rate, I've re-read some of your posts in the thread and it dawned on me that you're still in elementary school, or close in age anyway. The "mom" part of your screen name threw me off. I do think its noble that you want to save animals that you may perceive are being harmed, you just need to do it responsibly. IMO you have a tendancy to maybe "fudge" the facts a little to make your point. When urging people to take action, you really shouldn't.
Some examples might be:
*In one thread you accused one of the chains of putting blue food coloring in the betta cups as if you knew it to be fact. When other forum members pointed out that this was unlikely, you claimed to have overhead two employees talking about it...even claimed that the blue tint in the water dyed your fish. All of this is very unlikely, and when something is very unlikely and illogical usually its not true.
*In this thread you said that the school was going to flush the fish at the end of the project. I would suspect that not to be true...maybe it is, but you should have at least confirmed that with the principal before posting that the named elementary school was going to be flushing 60-70 live fish down the toilet. I know that you may think you have all the facts from your friend who attends the school....always best to be sure before making statements that might inflame tensions. Some folks here were even urging you to call PETA & ASPCA based upon this. Talk with your parents first before sicking these organizations on the school.
I know you don't think so now, but posting the name/number of an elementary school in a thread with the potential to incite action really wasn't a good idea. With all of the craziness in schools today, the last thing schools need is the potential for violence. While this violence may be unlikely, the potential still exists. I'm sure when you have your own kids you'll likely agree.
I applaud you for your conviction with regard to saving animals. Just remember though, when you look for folks to join your cause (like you did when you urged everyone to call the school), just make sure that you're giving all the facts.
Good luck with your new goldfish!
