I have bred these in abundance, Ps. annulatus Guinea.
I like to keep these in a heavily planted tank with fine leaves including Hornwot. and Java Moss. The males are rather aggressive toward each other and the added plants afford respite for smaller males.
The set up I use is 18"x10"x!0" bare bottomed tank with a small air driven sponge filter heater set to 74'F, pH is in or around 5.5 to 6 subdued lighting can be achieved using the floating plant Salvinia.
The eggs are very small and I dont like to handle them, hence the setup as above. The hatch in or around 14 days. I try to fish out the small fry from the edges of the tank but leaving then there will result in some predation by larger siblings. (but you will have more than ample stock using the above method.
Feeding adults due to there small size presents a few problems, I like to feed live foods ie: newly hatched brineshrimp small white worm and best of all vestigal winged fruitfly. Feeding the fry in the above set up due to their minute size means that the plant matter will proved the fry with small foodstuffs, infusoria etc. until they can take newly hatched brineshrimp, vinegar eel and microworms.
They are a small species but under the correct conditions the males are stunning, You should be able to sex them after 3-4 months and they will be breeding after 8-10 months. Regular waterchanges and cleanliness is an essential part of the husbandry involved in keeping these little jewels.
I hope this was of some help to you
