Ok I got the test results-
Salinity- 1.019 (idk why it's that low I'm adding more)
Nitrates- 20 ppm
(water change is tomorrow)
I don't have any larger shells. Where can I get some for them? I have a couple of turbo snails but the snails are HUGE, at least 5x larger, so I'm not that worried.
The larger is fine. He's dropped his shell completely and is just looking for food now. The second still hasn't moved but I'm starting to wonder if what I'm looking at is the actual crab or not, I need to look a bit closer. The last snail I have found and his shell is still on.
