Cleaner shrimp

I've had a drastic ich outbreak! And lost a sailfin tang flame angel and a rusty angel. The display tank has been fallow(no fish) for about six weeks. In the DT is one cleaner shrimp one blood shrimp and two peppermint shrimp. 55g reef with some asstd coral. My question is has anyone had any experience with a cleaner shrimp harming any coral in any situation he is pretty busy all over the tank and I'm thinking without any fish arround to clean up after he may be causing some mischief
Any thoughts?
Thanks any advice is good advice

 

No, those shrimp are completly "reef safe" You should not have any problems with them. The peeppermint shrimp can be though. They like to try to eat things that look like aptasia but are really not! Sometimes they will and sometimes they wont. It is a gamble. You should be fine with the blood and cleaner though.

 

You should be feeding the shrimp. Just a small pinch of flake once in a while is fine.

 

Shrimps get fed almost daily with a pinchof flake or mysis while I'm feedin my dendro but he does like stealing the mysis right out of the dendro . Kinda ticks me off
Oh well natural eh?
