Welcome Jash! 
I don't know the vernacular name Watermelon crabs but if they are fiddler crabs please give them brackish water fast. Some fiddler crab species are damaged permanently even from short contact with fresh water.
The tank sounds alright from the other aspects but the moisture must come from salt water. Maybe something between 15 grams per litre and the marine concentration, 34 gr/l.
Crabs abundant in HK You can see here, 6 species of fiddlers listed: http://www.afcd.gov.hk/english/conservat...html#crabs An essay about fiddlers in HK You find here: http://www.afcd.gov.hk/english/publicati...les/12.pdf There is much information about their life, behaviour, habitats etc. You should be able to find out if Your Watermelon crabs are one of these. They will eat nearly everything: Flake food (for fishes), algae, dead fish or little crustaceans…
Sozialicing crabs normally is no good idea. Some Sesarmids can be sozialiced as well as specimen from one species but there still we be some aggressivness because they are territorially. Nevertheless, some fiddler crabs also can be sozialiced but we don't know much about this topic yet.
