It seems to be the night for questions re: identifying hitchhikers. I discovered my own today with the appearance of a multitude of tiny white or near transparent ones crawling over my LR and LS. It appears that they've got 8 legs and 2 antennae and at approx. 1/8" - makes it hard to see, not to mention counting legs. They're appearance doesn't bother me as much as the apparent "egg sacks?" hanging from LR in various places. These "sacks" may extend downward as much as a 1/2 " and seem to be plentiful. The 55 gal is in its 5th week of waiting for the initial cycle - will it ever occur?- . Ammonia, nitrate and nitrite are all zero with a good ph. I've haven't read anything about these critters and I'm concerned if the sacs break and the tank is filled with these guys. Any ideas?
