[quote=”Peter Finke” post=915]P. parvulus as P. ornaticauda may be a bit difficult. Sometimes, it works at the outset, but sometimes it will not. It would be of advantage if you could look into the cave in order to see what happens with the eggs. Could they be fixed at the top of the cave by the male or do they sink to the bottom again and again? This is probably due to wrong (too hard) water. Do they disappear after one or two days? Mostly it is impossible to get the cause clear. But there are observations (e.g. from Horst Linke and myself) that a very low pH could help. Master-breeder Günter Kopic once had success only with a pH of 2.8!! This pH has been proven by control-measurements with several electronic equipment. However, I would not repeat that experiment. But a pH from 3.0 on upwards is surely possible. In my case the eggs did no longer disappear when I lowered the pH from about 5.3 to 4.4.
But there can be quite a number of other causes. In your case everything may be in order. Two days after spawning the young are not hatched.[/quote]
Hello guys. Sorry for disappearing and now barging in. Kind of held back by tonnes of work lately.
Anyway just to add in a bit on my recent experience with P parvulus; thanks again to Olivie “Olie” Perrin.
I has 3 pairs in a tank and had the first spawning (2 pairs) in November which coincide with the monsoon season. Another pair spawned last month, again it was raining for a couple of days before I notice a clutch of eggs. On both occasions, the temperature was at about 24-25C (it’s usually round 27-29C on most of the days)and the pH was noted to be about 4.5-5.0.
At the moment got 4 fry from the first spawn and 8 from the last brood. Hmm..not that difficult I think. Hmmmm.. :whistle:
