They will be lighter with lighter substrate - but it doesn't always have to be that way. Mood can affect coloration and also the dominance structure among the fish and also the presence of females emitting pherimones can have an impact too.Jesseschu said:Hi there! I have an adult Calvus Black Congo I recently purchased. He is a great fish and I put him in my show tank 75 gallon with a mix of other males. He is only doing average in this setting, as he only gets leftover food and is washed out color wise with the white aragonite sand.
So I think I would like to put him in my long 20 gallon and create that tank around him. Would you be so kind to help with:
1. Substrate: I have heard a black congo looks great with black sand
2. (more importantly) Companions so he is king of the tank
thank you very much in advance for the assistance.

If you were to do a black subtrate, I suggest CaribSea's Arag-Alive line, they have a Hawaiiam
Black aragnite. Petco has an offbrand they keep on the shelf. I have been doing some jumbling around of fish and tanks lately. I have some calvus bcwp, temp, in a 30 gallon with tahitian moon sand. I'll take some pics this weekend. I will also put up some pics of the same fish over a light aragonite (if you want me too???).
