Should i keep gecko as pet?

There are a family of small light brown geckos living in my air conditioner and sometimes they have babies and I get tiny baby ant sized geckos walking around.

They are very cute, don't do any harm and if you get too close to them they run. Never really seen the big geckos because they hardly ever come out, and even moving slightly will scare them and they will hide back into the air conditioner.

I saw a little baby gecko just now and I thought about catching it and keeping it as a pet, sometimes I catch them but I don't kill them I just put them outside.

Do you think I should do it? I would get a big enclosure like a snake enclosure and feed them and catch another gecko or two so they aren't lonely.
