Was it so hard to just let it be that I believe the water is safe and leave it at that? Also he isn't eating the moss, when he grows and becomes a good eater I will remove the moss, until then there is no risk. You guys are making it sound like I'm just bashing down everything you say to me. The only things I am not following advice on are removing the moss and changing the water. I am confident they are not what is causing the issue so it should have just been dropped and moved on from the beginning.
