I just picked up a juli, or referred to as the 'masked gombi'. I have him in a
20L with a sandy substrate. In the future I would like to try and breed them. Is there any physical characteristics that are discernable if they are male or female? I've looked online quite a bit and can't find anything!! Also, about ph buffer, (increasers) how do they work and what brand is a good one to try for cichlids that like a really high ph?
