I moved my sav into a new tank about 2 months ago and every time he deficates he does it in a large soaking pool I built into the front left side of his tank(see pic below). I noticed a thread a while back (Pics: New boy and old girl (hopefully) - rappstar609, Aug 26, 2008 ) where this issue is throughtly discussed and debated. With the conditions in my tank there is very little possibility my sav was dehydrated and plus I see him drinking water regularly so it just didnt make sense to me. Well The past couple days I decided I wouldnt fill the pool with water I would just leave it empty. Well what do you know he still went in the pool even though there was no trace of water in it. This makes me believe, in my case, that its habitual/preference. Maybe, however it sounds dumb and unlikly, its kind of like a litter box type thing, when he deficates there its out of the way and not where he usually occupies as you see from the pic. I just thought Id share the results from my little experiment.
