Zoa eating Amphipods!

[Regric25]

So I am at work and my wife sends me an email explaining that there are HUGE amphipods in the tank. I went to explain to her that they are harmless and not to worry. She said she saw one on a colony of zoas and decided to do some reseaerch. She found out that some amphipods can develop a taste for zoas and palys!!! I had no idea! Maybe this is why sometimes part of a colony might close up and not open for weeks... I did some reading on my own on wet web and it says some are known to eat them.. Luckily I don't think I have this issue because all of my coals are happy and growing. Here is a link http://www.wetwebmedia.com/amphipodfaqs.htm

ALSO, I noticed some flatworms on my glass in my tank about 1 week ago. None of the corals are damaged and all of them are doing great. I have no idea how they got here because I have not added anything to my tank in a loooong time. Its been at least a month since adding anything. They don't seem to be doing any harm to the tank and the numbers are not huge or anything. It's just something I have observed in the lat couple of weeks.

I don't have any fish in my tank and so pods and flat worms are roaming fear free in my tank. I was wondering if there are any fish out there that would munch these critters. I don't want a wrasse since they are known to jump. I have a 20 gallon tall tank. Any suggesions are appreciated.

I read that mandarins eat both of those and sixlines.
