Did you get your Chocolates to breed?
No, but I didn't have the proper setup to do this with (e.g. an RO/DI unit). I didn't have the funds for one, either, and even tried collecting rainwater to use in the tank, which was a huge pain. Actually, so little is actually known about this fish (a whole bunch of wive's tails abound on the internet from what I've seen). This fish is classically labeled as shy and frequently bullied by other fish, which it is. However, no one ever mentions (and may not even know) that this fish is EXTREMELY violent towards its own kind. I had a nice group of them in a 20L...and over a few weeks, watched the top fish systematically kill those below him in the heirarchy. There is actually a good article on their behavior in the latest issue of Tropical Fish Hobbyist, and the second part will be out next month. The author has actual experience with this fish, and attests to its violent nature toward its own kind. Many individuals need to be crammed into a tank that is PACKED full of hiding places and wood. It's not what most people would consider a show tank...but I love it anyway. \
But back to your question: I never got them to breed, but hope to some day. I have contacted a few people overseas who have, but I think places like the Netherlands and Germany just have a magic wand they wave over the tank to get their fish to breed...and they're just keeping it a secret.
Have you ever seen some of the other species of Chocolates? They are even prettier!
Personally, I wouldn't go that far. I don't base "pretty" by the brightness and number of colors on a fish. I'll take S. osphro osphro over Valliant's or any of the others any day.
