Still too early to tell. The QT lights stay off 24/7 as it renders the medicine less effective, not to mention makes him more comfortable. Light breaks down the properties of Furan. Once the ambient light hits the room where the tank is I'll be able to look in on him. I hope I see some sort of improvement, no matter how small. I'm really hoping to get him to take some food today. I've got some nice yummy live blackworms for him, I hope he takes the bait.How's he looking today Kym?
