Best repltile/amphibian for newbie?

[WhosGizmo]

I'm interested in getting a new pet and have a length wise tank just under 200L (55 gallons if preferred) - I was hoping for suggestions on little critters that would both be suitable for my type of tank as well as my still developing knowledge about their care.
I've done research and the sort however I feel I should still start from the basics.
Any and all input is appreciated.

The best pet for you depends on what you like and what you're capable of. For some it is a fish, for some it is a cat, for some it is a reptile, for others a girlfriend would be more appropriate. I can tell you what's best for me, but without knowing you, I can't say what's best.

Basing it on 'I have a fish tank and want to put something in it' is rarely a good start.
