hey guys I was wondering if anyone knows what I can use to glue down corals in my tank? I know eddies sells an epoxy but it is 25 dollars for a tine tube. I remember someone telling me about stuff at home depo that you can buy. also how long does a fish have to stay in a qt tank? I have my sisters hippo tank and my naso tang in my 40 long . no signs of ich and both are eating well. I am just not sure if it is 3 or 6 weeks. thank you
