It has been written within this forum by people far more experienced at breeding Parosphromenus than myself, that the male should always be left to tend to the nest.
The eggs will not hatch without his care. The young fry also need his care to develop in the first few days. Once they turn dark they appear to be strong enough to fend for themselves. I start feeding with small food ( banana worms) as soon as I move the nest.
In my experience, they darken and leave the nest within 3 to 5 days. I don’t know if this is dependant on what species, or other factors.
So Rafael, keep a close eye on their development , it may be quicker than you think.
