on friday I stopped all treatments, today I looked and he still has that open wound, can it be an open wound caused by another fish or a deco? if this is a wound or cut like humans gets does it heel or will it stay like that? is it ok to start second week of treatment and see what happens next weekend or to just place him in the 75g main tank again?. I really dont see him eating but he is still alive and moving around, just that sometimes he tends to lean towards the wound side but has been this way since I put him in the qt about seven to ten days ago.
