my apologies Chris, i am a bit behind on my forum stuff. if you do the 10g vert, then a pair of tincs is all you want to put in it. in fact, they should normally only be kept as pairs. that being said, as far as lighting, heating ect. a lot depends on your design. what look are you going for? there are a couple excellent stickies at the top of this forum about the vert conversion. give those a few reads and see if they help. if not, we can definitely delve further into building your tank![]()
