Thank you Stefanie for the links, – I have seen the thread you are mentioning, unfortunately yes, it is impossible for me to really understand.
Martin, – thanks also for answering. Its an interesting theory, –
But also for me its the same conditions in all tanks, – and I have 8 species, only with the harveyies is the problem.
And I might breed extensively 🙂 but I feed ‘intensively’ .. meaning I probably way overfeed, – would that not help this problem. Unless its in the very early stages as you say before the fry take any artemia.
I certainly will be aware of it in some way.
