My tank at work...

 

[SPLiSH]

The 11th grade Bio students have a tank in every science classroom, they look about 50 gals. Us 'inferior' 9th graders aren't allowed to help with them even if they're in our homeroom or such, because the science co-ordinator thinks we'll kill the fish. Bit rich coming from him since he's managed to kill 2 bunches of platies this year. They don't believe me when I say you're not meant to switch off the filter overnight.
