Well now for an update on Charlie...
The Cycle's over!!!
I just did the tests and as follows:
NH3=0,
NO2=0,
NO3=5
However he's still being rather reclusive. I do see him out periodically but he seems to spend most of his day hiding.
After a bit of Googling for reasons why he might be hanging around the bottom of the tank I've found the following.
1) Water Paramenters -nope not this as seen above
2) Parasites - could be a possibility
3) Strong Water Current - another possilbility I'm currently looking into but my filter doesn't seem to have an adjustable flow so I'll have to modify.
