hello all. Thanks for all the help getting my tank cycled. I have just adding some news things to my tank. Fire shrimp, emerald crabs, a few snail and hermits. I️ also adding 4 zoas(not sure about type as it was a pack), GSP, a ricardia mushroom, and two leather corals(one looks like a tree.) I just have a few questions. Should i feed the corals and what type of food? Should i feed the tank(flake food)? And what placement is best. I have all the zoas low, except one I have up high. Everything else is mid to low. I️ I also turned my radion down to 15%, guy at my lps said 50 was too high. Is this appropriate? My flow I would say is on the low side. Thank you reep friends!
