Sorry to hear about your squished fry. I've accidentally thrown out my only brownorum fry into the front garden and it is horrible when these things happen.
Sounds like you've got a fry factory going on there. At least the fry from the bigger mouthbrooding species are a decent size and can take foods like BBS usually straight away.
Better give your albimarginata a stern talking to. I'm sure they'll get it eventually. Then you'll wish they would stop!
I finally got some photos of my macrostoma male coloured up. He is not fully coloured up as he doesn't like my camera but it is better than the last lot. His female has also coloured up as you can see. If she colours up any more I may think she is male.
Also got some photos of my brownorum female. Excuse the hand, it was the only way she would sit still.
Burdigala female had to go into 'prison'. Her and the male look like they have been at war. Just going to let them heal up before I re-introduce them. Of course the male spends all his time flaring and preening in front of her still.
