[German blue ram sexing?]

Okay, I'll keep an eye on their development. I have a 180 litre tank that's heavily planted (40 gallon, the dimensions are similar to a breeder tank) so they should have plenty of room to mark out territories but I keep an eye out incase I need to re-home/return one. 

I'm not planning on breeding them, I just love their behaviour and appearance. 

I've also noticed something as I was watching them yesterday. The bigger one isn't chasing the smaller one away as much. If the bigger one does turn to chase the smaller one will back away a small distance and that seems to appease the bigger about 60% of the time. If they do chase them is a much smaller distance.

[German blue ram sexing?]

Hi all,

I need some help double checking the sex of my two German rams.

I got them from a very good aquarium shop where I live and ask for a male and female but the person helping me said it harder because they are quite young but was maybe 70% confident they pick a male and female. The reason I'm worried is that the one a believe is male chases away the female when he notices her unless he is too distracted by feeding time. 

The first two image is the one without a spot and bigger, but is generally confident (will approach the glass). Second two images is the smaller one with a spot but spot has blue over it. (They are harder to get pictures of because they are shyer)
