Hi Josh.:wave:
Not familiar with QuickCure. If it has copper contents, I would try other medicines other than that. Copper can greatly harm your shrimps.
Try to increase the tank temp to 30C. Treat your whole tank and try to avoid stressing your fish. The more stressed your fish, the weaker their immune system will be thus the ich will succeed in killing your fish. Continue treatment for 2 weeks. The longer, the better just for precautionary measures.
Consider giving your fish nutritious foods to strengthen their immune system to fight off ich.
On the side note, ich is at its most vulnerability if it is in free-swimming phase. Meds are not effective when ich are encrusted under the fish's skin. The warm temp should speed up their lifecycle thus enabling them to go to free-swimming stage in which meds can destroy them easily.
Good luck.
