With severums (the majority that is) the males tend to have facial markings of squiggly lines etc, where the females tend to have plain colouration, however with the gold and red spot severums sometimes the females will sport some facial markings under the eyes and on the gill plates, with yours being either a light coloured juvi red spot or a gold its quite difficult to tell the sex from that angle on the picture, as both pics have light across the area between the eyes making it difficult to see any markings to be 100% sure of the sex.
