Harlequin Shrimp... Most LFS will have pairs for sale from time to time... ML have harlequin pairs from time to time...
Not sure about boxer, guess those with eggs are female, those without are male... But advise you not to have boxers, as they are very aggressive and will attack other shrimps...
For Clam, not really sure... Not really keep them before...
For Soft corals, 55w pl is enough liao...
But the more the merrier... lol...
Bubbles are not Soft coral, they are hard coral, LPS...
