How much colder than 65 degrees?

Digestion can be so slow at lower water temps that food may spoil before being digested, IIRC. But I hazard to guess that any water temp which coaxes CNBG to feed on pellets at the surface is probably OK.

Quantity and frequency of feeding should be lowered as the temperature drops.
