You must ask yourself “what kind of statement am I making with this tattoo?” After you have answered that question ask yourself “does every facet of my life reflect that same statement?” This is why, as a Christian, I don't drive around with a fish on my car - I know there are times I'd embarrass Jesus with my reactions to city traffic.
But then, that fish may give you pause to drive more carefully.
BTW, I like your screen name. ¿Tu habla español?
