Hi All

I have a 4.5 gal. Tank and want to get a good adjustable heater.

I would also like the heater to be protected from my idiocy, in that I may....forget to unplug before draining the tank for a water change.

I gound an Eheim heater that is almost perfect, but it is too long. The 50w is around 10" long!

Anyone got not her option, say n the 7" long range?

Thanks for all your help.
Cheers
