grey

About a month ago I got some red cherry shrimps They was all a nice colour of red although there was some tiny little ones in bag that didn’t really have any colour Today I’ve noticed 3 shrimp that look like the picture and the other shrimp I can find are all bright red Is this a different type...

Hi Guys,   The stuff attached in the picture has been growing in my planted discus tank. What is it? And how do I treat it?   Best wishes,   Cameron
