My tank is over a year and my other corals are thriving . Params are perfect and very stable . Doing weekly 10% wc. 2 nights ago I saw a big amphipods eating my zoa . These suckers are killing my zoas. I have tons of amphipods in my tank.

when you say perfect? WHAT are they?

How old are you lights ( bulbs )

if you have one of those frag racks, you can move the frag of RDs up there to get them away from the sand or main rock work where the large ampipods usually inhabit.

you can also get yellow or green coris to eat up those large ampipods.

Yes they are.

I would try a lugols dip if you have or a fresh water dip.Sometimes a little swish of the zoas in the water will get any particles off of it
