This week I have not that much time to read and write her on RS, sorry Cat. But now I have to make once again a few comments.
As the first note, the water in a breeding tank should always be fresh and filtered. In a breeding tank should never be the first weeks any ground/LS, or any decoration/LR. Since the first days always larvae die you must soon remove dead animals. In a tank with LS / LR but it is almost impossible. Also one should remove daily the feed leftovers, in a tank with LS/LR almost impossibly. Another reason why one in principle a tank without decoration should use is, one sees the small larvae much better and can judge thus their state of health much better.
Ah well, hopefully one day my clowns will finally get along and I'll get to learn all of this first hand! You're so lucky Cat!
