Which cold water killifish are you keeping and at what temperature? Many cold 
water tolerant fish are not active unless warmer - they are cold blooded and 
their metabolism is slowed at low temperatures - they are essentially dormant. 
Many killies are not tolerant of higher temperatures, because they need more 
oxygen. Perhaps you should consider somewhat higher temperatures but with 
increased aeration or higher surface area tanks. I collected many Austrolebias 
this past July in Uruguay in water that measured 4 degrees C. These fish were 
active and healthy.
