Heya, So I have a couple of essential oil bottles lying around that I don't really use and I was wondering if I could use some for my crabs. Like eucalyptus or sage or lavender. I also can get some fruit oils as well. Since they are very concentrated I was wondering if I could put a drop or two on their food. People seem to say that they are attracted by smell. There are no other products in the oils other than concentrated extract of .... (insert flower, fruit). What do you think?
