my rb's are so skittish they will not come out to swim around or eat or do anything. i have three of them in a 55g tank. all they do is hide in this tree stump together and wait for the lights to go off. i have the tank in a fairly high traffic area and ive dimmed the lights with aluminum foil and my water temp is about 80-81. would it be a good idea to take out the stump for a while or would this be stressful. by the way my reds are about 2 or 2 1/2 inches long, but theyre growing nicely. thanks for your ideas.
