I've noticed lately that my boy King Gus has taken to lounging around on the upper most parts of two plants situated in the rear left corner of his tank, He seems pretty chill (relaxed not cold). It's been a while but I think this is normal right? He's near the top of the water for maybe an hour at a time then commences his rounds of his environment here and there, but he does enjoy resting in the corner near the top.
