I think so? I don't know for sure, mine does that too so guessing it is? Mine found 4 leaves on one of the plants and stretches across them like a hammock and lies there every once and a while. Then it's back to swimming around like normal.
alright, i made a cave out of 3 rocks and he goes under it and lays on the gravel. also are they possible herbivores too, mine nibbles on my java moss quite frequently
Mine does the same as well but once i go close to the tank he jumps right up so Im guessing its natural I mean he does move constantly with that single fin so im sure he gets tired at times.
