Perching on plants?! Wow. I mean, gobies do that, sure. But a catfish? Awesome!You are right about that. Mine seems to change his tactics whenever I change the tank around. When he lived in a 55 gal (as a little guy) he alternated between sitting in plants and hiding but always came out for food.
Now that he's in a 150 gal (and about 8") he spent the first 6 months hiding in rocks and now he's decided to suspend himself on top of the plants. My friend thought he was a fake rubber fish lol.
Very quirky catfish but I've found him to be fun (We named him Old Gus).
