Urgent help needed - need insights from experienced members of the community, inverts dying
In the last few weeks I've lost 1 of my Trochus snails & 3 of my hermits.
I don't know if it's for the exam same reasons, as my hermits disappeared, and I discovered My Trochus dead. I've discovered a 2nd that seems very weak. It was on its back and it dropped off the glass when I placed it there. Attached is a picture of said Trochus right before it fell.
My inhabitants are (as of right now):
- 3 bumblebee snails
- 4 Trochus snails
- 2 fire shrimp
- 2 cleaner shrimp
- 1 Randall's pistol shrimp
- 1 electric blue hermit
- 1 toadstool leather (1 week since to tank)
- 2 zoa frags (1 week since to tank)
- 1 Dracula goby
- 1 scopas tang (1 week since introduction to tank)
- 1 leopard wrasse
- 1 Mccoskers flasher wrasse
- 2 bangai cardinals
- 1 elegant firefish
- 2 common clownfish
I very much suspect the wrasse may have had my crabs for lunch.
I also have a refugium with a pod population that's about 4 months old.
225 litre tank. The afore mentioned crabs and snails had been in the tank for about 4 months.
I feed the tank about 40ml phytoplankton into the refuge and 12ml of all for reef into the display on a regular basis.
My fish seem healthy - very active swimming, no aggression between them, fed a couple of times a day, and my shrimps and electric blue are much the same.
The polyps on the coral are a little shy but I'm chalking that up to the fact that they're relatively new.
My Parameters as of right now (as I literally just checked them):
SG (salinity) 1.025
DkH (alkalinity) 9
pH 8.2
Ca (calcium) 380ppm
Mg (magnesium) 1380 ppm
NH3 (ammonia) 0ppm
NO2 (nitrite) 0ppm
NO3 (nitrate) 40ppm
PO4 (phosphate) 0.25
I don't want to see the rest of my tank die but I'm feeling clueless about a diagnosis here.
