What fish did you want to keep?
What are the tank dimensions (length x width x height)?
What is the
GH (general hardness),
KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website (Water Analysis Report) or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg:
ppm, dGH, or something else).
The Congo River is normally soft acidic water and can vary from sand to rocks or gravel. It might have driftwood or rocks (wood normally where there's sand, rocks where there is gravel) or there might not be any wood or rocks. If you want open water fishes, have some smaller rocks around the base and most of the tank open for the fish to swim around. If you want bottom dwelling cichlids they can have rocks, caves or driftwood.
I don't like plant substrates especially if you plan on keeping bottom dwelling fishes or fish that dig. Plant substrates are mainly for heavily planted tanks with a few mid to surface dwelling fish, or no fish.
