Bay Blenny incubation period - 06/05/09
Hello WWM Crew!
My family and I are wondering if you could tell us what the approximate incubation period is of the Hypsoblennius gentilis (Bay Blenny of Southern California).
Thank you,
Tom

Barnacle Blenny Eggs Blenny Reproduction: 5/21/2009
<Hi Whitney>
I'm having trouble finding information on hatching barnacle blenny eggs, is it really just too tough?
<Not as daunting as theoretical physics, but certainly more vexing than raising guppies.>
A little about the system I have, its 70 gal, 40 gallon reef circulating water with a 30 gallon "display" refugium. In the reef tank I have 3 barnacle blennies. I just noticed this morning that inside one of the barnacles there are lots of tiny black dots lining the wall, then noticed they came in pairs of two along with a membrane around each set, eggs!!!
<Neat!>
A blenny hangs out in the barnacle since I noticed the eggs and he (I assume) constantly is doing a funny wiggle trying to get fresh water around the eggs (I'm guessing).
<Likely so.>
The reef has strong current and bright lighting with lots of hiding spots.  The complete opposite in the refugium, some rockwork but mostly Caulerpa, Chaeto and various red macros in dense bunches. There is a chromis and Pseudochromis in the fuge and a percula, midas, and vlamingi in the reef. Question is should I leave him and the eggs in the reef and kind of forget any chance of raising them or could barnacle blennies hatch with just a bit of care and modification to one of the systems? Would I have to start a new tank to raise them?
<You would have to have a separate system, completely free of any predators, as well as rotifers, or other tiny foods for them to eat. DO read here: http://www.wetwebmedia.com/feeding.htm>
Thanks for your help!
<My pleasure>
