Oh I love distractions. I didn't mean for my post to make the whole idea sound bad. Imagine how cool a tank with LIFE in it would be?

I think a biocube or similar in a classroom would be ideal.
I also propose a smaller sized tank for a couple of reasons. I agree that it is easier to move/disassemble in the event it is required. Also, it is true that something foreign may unwantedly end up in the tank, for this reason I believe a smaller tank is easier than a larger tank. True a larger tank is more stable, but in the event you need to do a significant water change, it's much easier and economical to change 20 gallons than 90.

If something foreign ends up in the tank, it's gone. Simple as that.

No worries. :D I like distractions like these:

They tend to get their attention. :D

high school science class = plenty of chemicals that dont belong in the tank. If the students now are anything like i was in high school those fish will have a very limited life span.

As mentioned before, the tank is going in regardless, and any mucking around will simply involve the removal of the tank.

I was one of those kids that used to think that way although I have self-control....so I know lots of their tricks. lol

BTW...I have been given permission to include some venemous stuff like lionfish, as long as the tank is locked down. Now, before you jump on the bandwagon telling me that I shouldn't be doing that, please remove all the zoas and palys from your tanks. :)

I've got a bunch of bloody palys you can have, lol. They are almost as invasive as aiptasia.

Sure thing....let me know if you're coming down this way anytime, and I'll do the same if I am heading your way. :)

Classroom tank pics
 

Thought this thread had died down but have managed to get a few pics of the tanks in my classroom ....and yes, there are palys in there :biggrin: (Note the blue gloves in the first pic!)


Front corner of the classroom. Empty acrylic will be for a peacock mantis once I find one. The exoterra currently has an orchid and a tropical pitcher plant in it (a work in progress).

+1 think of the ADD students..... they got it hard enough as it is let alone with a distraction like that. if you do it, put it behind the students to help divert their gaze when it should be to the front of the class
fyi im an ADD student or was anyway now im just ADD....what was i talking about?
