Hi reefers, would like to know what are the symptoms of a bleaching hammer coral? My hammer coral is those brown with green tips. it always open up very nicely, but i can see tru the brown tentacles. they tentacles of the coral are still brown, but can see tru abit.... is it bleaching? how do i cure it? have tried feeding it pieces of prawn....but it doesnt eat prawn? lol. everything looks very good except the colour. it looks abit transparent...or is this normal?
