You did a really good job with your pic, he's a cute little guy. Kuhli's are great clowns to have in a aquarium!! I thought I'd share some info I have learned that you might find usefull. First off because Kuhli's have such a small bioload you can have more than you thought, the 1" a fish rule does not apply!! They do best in groups of 4 or more and if you have a group of Cory Cat's you will probably see your Kuhli's a lot more often. Kuhli fish are nocturnal but having the Cories seems to help them feel more secure so you see them more often. There also are times when you stop seeing them except in the evenings and other times they're out during both day & night. These are very interesting fish but the info available on them is limited.
Once I had a Kuhli & a Cory in a quarintine tank and I saw them playing with each other; both of these fish have clownish natures and are fun to watch. Snake comments are popular, every time my Mom see's one of my Kuhli's she says "I see a snake"!!
