I bought these mushrooms and ricordia yesterday. I have them both placed in the topish half of my tank. I have a 130watt PC with actinics and 10K with led moon lights at night (very cool). I've never kept mushrooms or ricordia before as I am new to keeping corals, so if anyone could provide me with any info that would be great. What type of placement they like, if they need additional food sources besides light, what type of additives (calcium, Iodine, strontium etc) they need. Just the complete 411 on mushrooms and ricordia. Thanks in advance!!
