Guys... breaking news!!!
A 360º change!!! Firstly, must thank those bros that show their concern over the welfare of the SH... after doing much research, 12G is indeed too small a volume to successfully keep SH happy... not to mention the limited vertical space needed for SH to move around... so I canceled the sales of the 12g NC... appreciate the kind bro (seller) for his kind understanding
I will go back to my drawing board once again... this time bearing in mind the needs and requirements of keeping SH
Any suggestions are most welcome
