They Are All At The Back!

[Colonel Mustard]

I have a quite hevily planted tank which is well stocked. I have noticed recently that the fish tend to hide at the back of the tank not coming out to the front they keep to the planted areas. My water is perfect and they are feeding fine. it is just slightly strange. Has anyonew else experienced this in their tank or solved this "problem"

thanks
