I currently have two beautiful black kulhi loaches (pangio oblonga) which i know is too few of them. I would like to get more but i cannot find any. I did however happen to find a regular striped kuhli (pangio kuhlii). I'm sure they will be fine in a tank together, but do you think they will swim and pile/play together like kuhlis do despite the appearance difference? Has anyone been able to mix these without a problem?
