Am I posting this in the right place? I just rescaped my tank a few weeks ago. I did another today. They are all.fake plants and buildings. Is it bad to rescape this often? Last time I rescaped, one of my Otto had died. In the following hours. He wasn't doing well, but could the rescape have killed him? I have one Otto left. (S)he is breathing a little funny and looks a little blue as normal after a wc. I also changed the water about 33%-1/3 of my 20 gallon high.
