I was considering "Cromwell" as a name, but may have to reconsider if he turns into a she. do you mean one of the 10-20gal ones or the smaller size? i've never been able to reach the proper temps using a side-mounted pad. the keeper is roughly 18"x12x7, so the 10-20gal pad is a little too large, but i'll try the smaller size and just crank it up all the way.
