So tonight I'm looking in my tank and for years not one problem and I looked at an acro I looked a little closer and saw little red things not moving just sitting there I am dipping it in coral rx should I put it back in after the dip or let it go into the trash can and what else should I do I can not see anything else that has them on there and anything around it look great any info would be great thanks in advance I'm sure they are acro eating bugs but maybe something else
