Ok can someone out there give me some info? I have 6 purple passion danios that I originally got in March to cycle my then newly planted tank. They are always spry and playful. Today I noticed two of them with whiskers????? They look like Kenny bin laden <my killer Bosemani> did when ate up all of my Amanos! SO my question is this...do Purple Danios grow whiskers or are they eating my shrimp too?????
