Hello! first time on this forum so my appologize if my answers can be found elsewhere.
My first saltwater tank is now 8 weeks old and I have added up to now 15 pds of LR
1 feather duster and 10 hermit crabs and 1 sea urchin. Oh, yes I have also added a 6line wrasse a few days ago... Now for my question, I have noticed that the parchment like tuke of my feather duster is being destroyed by the hermit crabs, leaving only a mucus like tube.
Can this kill the feather duster?
Also, I will be adding another 5 pds of LR
today, but just wondering if 20pds in a 25 gallon aquarium is sufficient?
Any advise would be great.
