It depends the frag was placed prior to your tank. A general candy cane will like a low to medium flow and lower to medium lighting. I'd put it somewhere with a subtle flow on the lower part of the tank to the mid. Coral can adapt to changes in flow and light usually but it takes while for them to get adjusted to the spectrum.I have blastos right now and one colony like low light and low flow while the other likes more intense lighting quite a bit of flow. Play around with it and try it in different spots if you have to. Trial and error
