hey everybody, i know fiddler crab care has been discussed on past threads and i have looked over those i have few more specific questions but i do apolgize if im asking the same questions over again. my family was recently in s.carolina so they brought me back 100 fiddlers. (there 5$ for 50) i set up a 50 gal tote with about 3 inchs of saltwater( i know brackish is better i will qradually reduce the salinity) the bottem of the tote is lined with huge flat rocks that extend out of the water so it creates a beach. there is more land then water and im adding a fine layer of gravel over and between the rocks. the only reason for the water being as deep as it is is to run a very small submersible filter. after reading nancys care guide for fiddlers im going add some sand soon. my major concern is the temperature. my room is around 65-70. will this be warm enough? how about lighting if any? any other sugestions would also be greatly appreciated. thank you in advance.
