Thanks guys,
To tell the truth I am no good at taking pictures and my camera is no good either (sony dsc-s50, 2.1mb).
After playing with the white balance, came out with this picture :

i don't know but the picture does not seems to show the actual colours..mmm
hi standoyo,
the krib and apisto seems does not bother the yamato at all, as you can see in the pictures below :

hi dom, really have been a 'fan' your works...
by the way, i am using just dc fan as shown in the picture below, manage to keep the temp 25-27C :
The whole setup really cost $$$, but worth it in a long run. I have been using plain holland sand before, and a lot of root stick, liquid ferts, but the growth and variety of plants does not seems at full potential...
Thanks
