They do best in densely planted tanks
I mean agressive with the other fishs. They not aggressive against their similar.
Kuhlis do fine in gravel, but for the best effect, sand is a lot better.. Mine love to dive from the top of the tank into the sand and all over.. It's a lot of fun to watch!Does the substrate seem to jagged for them? I'm never owned kuhlis but just a thought.
