In North Dakota's Bakken formation, the break-even cost has fallen into the $20s in some counties, the state's Department of Mineral Resources reported last month. Producing a barrel of oil would still be profitable at $24 in Dunn County, down from $29 last October.
You can exclude this risk. Water temperatures and influence on fish behaviour Normal temperatures for keeping discus fish lie at 29-30 Â°C. If your fish are too calm and do not eat greedily but are hesitant about eating, raise the water temperature for c. two weeks to 33 Â°C. This will raise the metabolic rate of the discus fish and encourage their appetite and their sense of hunger.
Into Action!! The best method to be on the way to a thriving well-managed discus tank is to set everything up and run the tank. After 24 hours, check your water temperature and adjust if needed (this should be 86f / 30c for keeping discus). If possible âseedâ your tank as already covered and leave to clear for a further 24 hours.
