Why are my crabs dying?
I don't understand why, but it seems as though my crabs aren't surviving my 3 month old tank.
I have had 3 crabs die in the past 4 days.
I know copper is the first red flag, but i have poly filter installed, so it can't be that.
Calcium is at 440ish? I'll check it again in a few to make absolutely sure.
Nitrates are a little high, maybe 20
Salinity is 1.024
Tons of algae to eat, and I feed the fish once a day, so they have plenty to eat.
My snails are thriving and eating more than ever.
I had an emerald crab looking awesome, then dead the next day. No slow deterioration or decrease in activity.

I wish I had your problem of only crabs mysteriously dying off.
Are you sure they're not just molting, and you're thinking the molt is the crab? It's happened to me a whole lot; my big hermit molted, and it looked like a whole body, but I saw it walking around 3 days later.

Hmmm that's weird. Are you sure that they are not molting. Did you checked the crab to see if there are any damage of some sort?

Two of them are dead. One was an emerald crab, and he pretty much disintigrated when i picked him up (and it wasn't a molt. he's dead for sure.)
The other one was a hermit, and he is definitely dead.
I'm not sure what to think.
