Alk is a bit low, should be between 8-9 . Hows you're ph looking?Thx for your reply. Got another foto with more white. My parmeters are normally 6-7 alk, 420 - 440 Calzium and around 1300 Mg.
What you mean by "dose" ?
?Anybody close enough to sting him?
In general, hermits are OK and maybe just picking at the dead stuff.Actually i saw some days ago a hermit crab (dont know if it is the right translation into english) on the head of a dead arm. I immediately removed it to the sump.
my coral looked super fine and then changed to this without changing/adding anyhtink in the tank
Edit: i could also watch now 1,2 2mm snails in a head of a dead arm (lots of them i have also during night on my front glass)
