So, I'm fairly new to the aquaria life, but my cousin is really big into it, and being handicapped I'm usually helping him out with this, that or the other, but he's slow about getting his stocked up, and I've got a 10g that I've decided to put a mantis shrimp in, probably peacock. Was hesitant to have just one thing in a tank, even for such a small one, and a buddy who has a lot of coral said he'd willingly give me a few pieces of some of his coral. I know a mantis doesn't have any lighting requirements, but coral do, and I haven't a clue what they'd be. The coral he's got, what I would be starting out with, are Green Star Polyps, Leather Toadstools, Yellow Polyps, and Colt Coral (Kenya Trees). If I have any room later I may add to them from the local fish store, but for now that's what I'd be trying to cultivate. So, if there's any tips or recommendations any of you guys could give me to make sure they stay lively and vibrant, I'd appreciate it. Thanks.
