Where are my inverts going?

Try looking for them at night with a flashlight. Lots of critters come out at night and flashlight makes everything stand out. I though my emerald crab had died when I found his poor lifeless carcass at the bottom of the tank. But the next day I found him hiding in the LR. Must have molted and was hiding. Anyway, you may find they are still there.

 

Check to make sure you don't have a Mantis shrimp!!!!!

 

If regular water changes are being performed, iodine need not be added.

That would depend on how many polyps/softies that you had. I have well over 4-5000 polyps of zoos and 300-400 ric polyps and I dose 3-5 capfulls every other day based on consumption(190 total gl). I try to keep it at 0.08 mg/l according to the seachem test. If I fall below that then I notice polyp closure/stress/stubborn attitude/slower growth. I do not dose iodide for crabs/snails as my investment is in corals-so I cant say yes or no to the health-as I have never paid attention to them(crabs-snails-shrimp). They all seem to do well in my system though.
Have you noticed any loud popping or snapping noises? Good luck!

 

I didn't even think of that! Where is my head these days
