Help Please

[RFD4]

I have some Tubbs, eagle eyes and Kedd Red in a BC 14 with PC light. Parameter are fine-

looks like the polyps are burnt and closing-

Do Crabs eat zoo's? HAd a bubble algae sac explode the other day could this be killing them?

Any ideas

Pics would be helpful...would also be helpful to post your params with numbers (especially pH and dKh)

Not sure what 'burnt' would look like, you mean the color?

Some crabs may eat zoas, what do you have?

Most crabs when small are pretty herbivorous, as they age and get bigger... there diet starts to morph to add more meaty products as part of it. They become opportunistic.
