What I have found is that there are differences, – sometimes a male will have a full nest and guard it very careful. I have a nagyi male, – he is very faithful, – I see him out of the cave maybe once every 3 weeks, – just for a day, – then he is back again on another clutch of eggs, and he has an extremely good ‘rate’ of succes, many offsprings.
Then other males, and you are right, young ones can be a bit insecure, – but they build the nest with a few bubbles, get a female to produce some eggs, then the next day rush off to get the female to come again, and produce more eggs.
I think on the little video I once uploaded of the linkei couple, the pair was mating while there were larvaes hanging from the first spawning. https://www.parosphromenus-project.org/en/forum/27-Undetermined/1173-video-of-attempted-spawning.html#1204
So what I am saying is, – that yes, he might continue the spawning in the same nest, – with or without eggs from the day before (they may have gone these eggs, – or they may still be there) – he may add to them.
I have never seen a male having two wives though 🙂
But I have seen one male getting either worried, or confused about too many caves, and actually moving eggs from one to the other.
