the rays look 100 percent better.I took the bugs off of the rays,I could only find one bug on each ray.I used my dads police flash light he gave me,Tweezers,a small net (which i used to hold the tail down and away from getting stung),and a magnified lens.i looked at there underside by using a glass mixing bowl.I used salt and anchors away.I always do water changes on these guys every day.They look great and are eating like pigs.
