Bro, both the convict tangs do feed on the hair algae, so as my 2 YTs as well. Was having hair-algae previously which is why I added the CT and YT earlier. Can find any of the algae anymore
But not too sure if it is group work or the CT working harder then the rest.
Update : Convict Tang sold. May consider to sell the 2nd one. Will update/PM accordingly.
