Temp and humidity are good, several digital guages
Ultrtherm across back of tank
Over 8" of sub, coconut fiber and playsand mix
Salt and fresh water, prime/instant ocean
55 gal tank with plexiglass lid
They get all the foods they need, replaced daily
Plenty of extra shells, @least 50 or so
No chemicals/fumes
Nothing new added, no sponges
I only spot clean
All PP's, had them roughly 9 months
All molted recently
Between small and maybe med/large?
I believe next to smallest one is the one that didn't make it
So... My conditions are good (EXCEPT my soaked substrate) and I believe my bubblers are causing the problem. I've read all through this forum and I'm working on fixing that now. I'm just trying to figure out why one of my babies didn't make it. Out of 6 crabs, 3 were up and 3 were about an inch... Inch and a half under. Noone was molting. They have plenty of room and were all spaced out all over the tank. I have 5 crabbies that are fine. One of the burried crabs was just a mushy looking, crumbly pile
