This fish is the male that I bought – and I bought it in august 2013, so a little more than a year ago.
This particular fish is the ‘father’ of now many offspring, – but the offspring is yet too small for any identification.
The more I look at this male the more I do think rubrimontis. But I will continue to try to make better photos. Its difficult to get good photos of this fish, because they dont show off a lot.
