six line picking on peppermint shrimp

[scrmom]

I just noticed this morning the six line wrasse keeps chasing one of my peppermint shrimps. Why? I haven't noticed the peppermint shrimp molting lately. Next question, the tails of the two peppermints look like they have died, they are black. They have been like that for 3-4 weeks now. What could be wrong with them? I have been adding iodine thinking maybe that needed help molting. Please help.

It sounds sort of like an Iodine overdose ... Are you testing before you add iodine/iodide?
As for the chasing cant help you there

I didn't start putting iodine in until I saw the black on the tail. I put a capful in once a week, and that is for 50g and I have a 75g tank. I haven't tested the iodine levels.

If you do regular water changes, there is NO need to add anything to your water.

I would not add any more till you test ... Iodine can be toxic. As Hara said water changes should cover that .... other than that I would suggest largish water change .... check your levels and check your calcium . Another reefer recommend that to me you may have high calcium/alk .

I agree here also that weekly PWC`s will take care of all your iodine needs. What are your water parameters?

My six line ate my pistol shrimp

How big was the pistol?

 

[divemasterjim]

he was small, less then an inch. He was a hitch hiker on my live rocks, was 2 years old

I think some wrasses will eat smaller (8 line definitely comes to mind) shrimp, snails and such, sorry to hear that!
