That would work fine~
I don't mean to be pushy or anything, but why not get the 5 gallon for $30? Instead of a 3 gallon for $40?
And I have no idea how 35GPH is, sorry. Is the filter adjustable? Or will you have to cram it with stuff?
I think I have heard complaints about the so-called built in filter and lighting, though. If it breaks, you have to replace the ENTIRE hood? I'm not sure, I've never used it before. But other than that, it'll work fine :)
