10g Palaudarium/Terrarium - is this a possibility?

[mgkaelen]

my 10g tank is soon to be empty and i'd like to make it into a palaudarium if possible. i would put something like neon tetras in for a small school and a crab or something that would have the land/aquatic capabilities. is this too small of a tank to make a palaudarium? i know it will greatly reduce the number of viable gallons in the tnak because it won't be 100% filled, i just think they're so cool. any thoughts on the minimum size to have a successful one? and tank suggestions if this is viable?

What about something like a 20 gallon tall, so that your water can be deeper.
