I have been reading about softies and all I see are people having trouble with them. What are the easiest to keep. What Shrooms. Zoos, corals, are the easiest to keep. I am not the best at keeping my prams perfect. I have a brown gorgonia doing well and something that looks like a small tree that is also doing very well. I just dont want to throw my money away. Any advise on getting a couple of frags of something very hardy?
