Newly hatched Berghia Nudibranch

[saucetart]

Can anyone tell me when newly hatched berghia nudibranchs would be visible to the naked eye in a breeding setup (no rockwork, just substrate and pots for shelter). Im seeing various answers & just hoping to find some clarifying information. Thanks in advance!

From when the eggs are laid, to when they will be visible, 4-6 weeks.
