Is a skimmer necessary in a frag tank

[GregW]

It's a 20g tank loaded sps & star polyps, no fish but I'm thinking of adding one butterfly. No supplemental feeding with food, just additives.

if it's plumbed in to your main system, then no.

If it's a separate system all together, every time you do water changes in the main tank, just dump the water in your frag tank. (if you do frequent water changes in the main)

otherwise, you may be able to get away with it, but remember, a skimmer provides two things:
water clarity and aeration.

You have no idea how hard it was going through all of those pictures on the internet looking for just the right bikini.
