I am fairly new to planted tanks. I am currently working on an 8 gal nano tank. I am very interested in Rotala Sp. Mini, but recently discovered that there is a type 1 and a type 2. I was wondering if someone could explain the differences between the two and also if anyone would have picts of each so that I could see the differnce. Do both have the same requirments as far as lighting etc.?
