Hi all, I have a 34 L Aqua one tank, I recently did the huge clean up in it, replacing a few plants and having a spring clean. Since I have done that, (I also bumped the temp up a bit because we are all freezing here) I have noticed these little tiny white creatures darting around the stones, mainly near the bottom. Are these good creatures or bad? Are they baby fish? They look like fleas but white!!! The fish are slowly picking them off 1 by 1. I have just been feeding them fish flakes and frozen blood worms as a treat! Im very new at this, my tank is only 7 months old. The big fish are in great shape, nothing to report there. Can anyone enlighten me?
