How to heat?

[pattyfurg]

So, I'm making melt own little fish tanks to fit into this bookshelf but I want to know if there would be any other way to heat it rather then 16 25W heaters.
My mum is pretty pissed off at the electricity bill because I used to have my fish tanks in the garage where it was 17 below and I guess that made my heaters work harder but she won't let me put the bookshelf anywhere else but in the garage :S

Can anyone give me any ideas?
(oh umm I'm keeping one fighting fish in each)

Would it be possible to build a sump that fed them all? And then just heat the sump?

Thats what I was thinking. A 20 gallon sump filled half way would be about 10 gallons then just add the volume of the 16 tanks together and buy a slightly over sized heater.

The only hard part is figuring out how to circulate to all 16 tanks.

It is one of the best filtration systems out there. You drain water from your tanks into a central tank with bio media and such then pump it back out.
Pumping it back out wouldnt be to hard. Just pump up one pipe and split it off.
