They are great little tanks. You are on a good track, but I would slope the substrate for a more dynamic layout.
Ya I have to go today and get more substrate that's all that come with the kit.
Maybe pick one large stone, then a few small.
The large rock is the biggest I recieved and the others are around the smallest I recieved. So I went with what I had.
What do you plan on keeping in there?
So far I'm looking at Cherry shrimp.
Also, how old are you man? Don't sneak around with your tanks. Be proud and wear them on the outside, like underpants.
See this is where the problem lies. I'm 21 and still living at home and going to school. :P I try to be proud and my parents are supportive most of the time but when I set up my 72 gallon the electric bill went up $50. Therefore, when they see another tank they are not happy.
