That's an Lq and it looks beautiful. Mine is the same color, Brownish and probably 3.5-4 inches long.
I keep my Lq's temp between 28-30C degrees during the day, would drop the temps to 20-22C degrees during night and humidity really dry (50%). I usually mist one corner of the tank and offer them water dish every 4-7 days (sometimes 7-10 days).
Female: 26-29 pectines teeth
