Have to be honest, not at all. He's pretty chill. He's active but swims in one area. Maybe because I have him in a slightly planted tank with lots of hiding spaces, but even then he's not very shy and doesn't hide.If I had to guess, the capa is not always comfortable. Does it dart and damage its nose or other parts?
They are not too hard to get onto pellets from my humble experience but nevertheless this is a nice accomplishment.
