This species and others in the genus are actually best in species tanks on their own, since they can all get feisty and fin nip, and a 20g is "small" space to such fish so this trait can be more prevalent. Substrate fish are usually OK with such fish, being at a different level in the water column.
Thanks Byron. So do you think this would be an ok set up for the fish to live a long and happy life? The reason I was looking at getting the bloodfin tetra is because they fit my water conditions perfectly and are really cool looking. The only thing that concerned me was the size. I am trying to find a tetra or rasbora that is around 1 inch and suits my water peramiters. It seems that it is only the larger fish that can live in a more basic water.
