Got this pair of Herichthys minckleyi in Germany Oktober 4. They where put in a 70 liter tank (temperature: 26 celsius, pH: 7,7 and GH 5-6). And 14 days later they spawned. The eggs was about to hatch after 3 days, but i could not see any fry as the eggs disappeared..
The day after – the male and the female was no longer interested in the spawning site…
Update: May 5. 2012
I now have about 25-30 small minckleyi fry swimming around in the basement (hatched January 15. 2012). The parents had to try 3 times before they where successful with the eggs.
The water parameters where/are the same as with the first two spawnings, except for the temperature, witch this time was at 28 Celsius.
