I just bought a lung fish yesterday, today i noticed he was swimming on top of the water. This isnt normal is it? why is he doing this? Also he is alone in a 29 gal. hes a south american lung and is about 2-3 inches.
when he says water levels he means ammonia nitrates etc and no dont add any tank mates mayb try some guppy fry or sometihng 2 c if he is only use d 2live fod
