Help! Big time newbie! <------

Ok, today I went to my LFS and looked at some plants. I found a low light plant called a Red Wendt(sp?) that the guy said was low light. He said he was running two 15 watt bulbs, so 30 watts. Are those good plants? Theyre kinda cheap so they could work. Also, I saw a fish there that I hadnt seen at any of the chains called a Livingstony, would those work with a shark and a the puffers instead of the TBarbs? Thanks!
