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.
If the eggs are infertile, they will turn white with fungus after a day or so. Fertilized discus eggs generally have a tan to orangish color. I wouldn't toss in the towel yet on them being infertile. Freshly laid eggs will be clear for a little while. This spawn would be a good practice spawn for both the discus parents and yourself. You can cull the baby fish later, but for now, let the parents take care of the clutch if they will.
