What will eat large amphipods?

[sbatten]

I have noticed my healthy colony of radioactive dragon eyes is not adding the normal 1-2 polyps a week, instead it seems they are disappearing. Last night i watched several very large amphipods eating them. I have seen my male mandarin try to eat them but they are too large. What will eat them? Right now I have 2 madarins and a cleaner shrimp (did have 2 peppermint shrimp as well but have not seen them in 3 days). I would prefer to not get a sixline wrasse due to all the stories I have heard about them being aggresive.

I love my melanarus wrasse. He is constantly on the hunt and cleaned up a flatworm problem for me a few months ago. Mine was an early addition to my system and has not shown any aggression toward others. I had a 6 line previously and he was a meanie. Most of the LFS around here have a melanarus in their frag tanks to keep the "bug" populations down. I don't know how big your tank is...the melanarus gets fairly large.

most large wrasse will actively hunt them but your cleaner shrimp would also be on the menu. Neon dottybacks will as well but they are pretty aggressive.

Following along. I have a huge population of amphipods in my fuge and would much rather have copepods populating there. I do believe the amphipods are eating any pods I try to seed there.

I have had this same thing happen.
Amphipods took over.
With that said.OP are you sure amphipods are eating zoas?This would be the fist time I've ever heard of this.

Most large wrasses are able to eat them, however they are usually not 100% reef safe.

Any solutions for a fuge?

I had 2 peppermint shrimp in my tank. One day I noticed some flat worms and I only saw them on my glass. A few days later I got a melanurus wrasse to take care of my flatworms. I knew it was a risk since he also might go after my peppermints. A few days later they flatworms were gone. The peppermints and melanarus lived peacefully and I never saw any problems so I went and got 2 cleaner shrimp and some nassarius and cerith snails.

It took me longer to open the cleaner shrimp bag then how long one of the cleaners lasted in my tank. The wrasse pretty much swallowed him whole and then went to work on the new snails. He also tried to go after a peppermint a few minutes later. The fish was a model citizen and then he turned instantly like someone flicked a switch. The very next day I gave the wrasse away.

On the plus side, I had to remove all of my rock to get the wrasse out and I took the time to rearrange everything and am much happier now with the way it looks.

In my tank everything eats Amphipods -- Angel, Tuskfish, etc. If I shake a few from the 'fuge into my display tank, it's dead before it can swim to the rocks usually.

My jawfish eats the ones by my zoanthids since his hole is right there

When I first set up my tank it stayed fallow for almost 2 months before I put any fish in. The amphipods got to be so abundant that there was no where for them to hide in the rocks anymore. I added my long nose hawk and he decimated them. He didn't eat any prepared food for 2 months. I know there hit or miss with shrimp but mine has been with my cleaner for a year and half and has been a model citizen.

My large blue green chromis are the biggest freaking pigs. They eat anything that moves and some things that don't.

For that matter my yellow tang, hippo tang, lyretail anthias and others would chomp them up too.

its hit or miss I guess, each fish is different
