I have had 11 CPD’s for about a month in an 18″*12″*12″ that were generously supplied by Albatross, I checked the tank yesterday and have so far found 2 fry of very different sizes, so I assume at least 2 spawnings.
The tank has a lot of java moss for fry to hide so there could be more, the tank is also very mature so should have plenty of food for the fry.
On the glass in the same tank were some other eggs which must be from the 4 Cory Pygmaeus that I put in there 2 weeks ago, so hopefully there will be a few young corys as well.
