Some may eat smaller shrimp, while others may not. Coral and small fish are of no worry
^^ after doing research it appears you are correct...
I just had an encounter with a lFS the other day where they lost a tusk and their reason was "he would not burry at night" so i was just going off hearsay i guess. That encounter sparked the question.
If this was the explanation they gave you I would suggest NOT buying fish from them. They clearly need to go and read some literature. :reading:
On the snails, is it just smaller snails, or are even large turbos on the menu?
Mine has been a model citizen and is actually a bit shy. Crabs and shrimp may not last long, but my snails are fine.
