Fat ass striped Raphael catfish.
These dudes will bulge themselves like this when they eat… and then you won’t see them again for a week. Serious. They are notorious hiders and you will rarely see one out during the day unless it is just to eat.
You will see some as large as like 10 inches online but I have never seen one over 5 inches personally.
Cool catfish in theory but you will rarely ever see it if you put it in your tank.
