I am no breeder of paros (by now – as far as I know. Depends on how successful my constantly courting pair of nagyi is …. 😉 ), only a keeper – but my fish seem to be healthy and really doing well. So I allow myself to tell my way of feeding.
My paros get small lots of freshly hatched Artemia every day, they are eaten within half an hour. Every second day I regularly feed glass worms (in winter, because you can store them in the fridge for quite a while), or, if available, Daphnia or bigger artemia. I feed approx. 5 – 7 glass worms per fish. They are eaten within two days and do not die, if not.
There regularly is a pause in my artemia production every three or four days (= once a week). Then I am able to offer micro or vinager eels alternatively.
In summer I can offer a bigger variety of life food – I have a garden pond that supplies rich food. But also only every second day!
