Check out this tank I found on the internet. I want to create a tank like this! www.nobobo.com. I'm about to start tank # 5 and it is a long 30 gallon I think. I'm going to have a lot of tetras and maybe diskus if I can find a good deal on them, and a few loaches of various types. It will have sand, plants, wood, and rocks for decoration and I'll use a 3 foot long 2 x 65 watt VHO flourescent light and a 175 gallon capacity canister filter for filtration.
