Bristlenose are said to be the easiest of the catfish group to spawn. I don't say that to downplay your success, which in my view is an accomplishment for any aquarist whatever the species; but more to indicate that you can expect the others to be more of a challenge.
I don't set out to spawn fish, but several species regularly do in my community aquaria, and sometimes fry do survive predation. I have had several spawnings with Farlowella, the Twig Catfish, as reported with photos in this earlier thread: Spawning Farlowella (Twig Catfish)
With one male and two females, I had spawnings continually for several weeks. Being in a large community tank (my 90g flooded Amazon forest setup) the fry had to be removed just before they hatched, or they were gobbled up. The difficult issue with this species is feeding the fry. They must have soft green algae. Following published reports using blanched spinach and zucchini, I tried those but without success. Still, I have 4 maturing fry in one tank that seem to be doing well and appear to be eating from tablets, and they are around an inch or just over. There are a few in the other tank from the last spawning. The adults seem to be worn out now, and have not since spawned.
