blenny eggs

[cf17]

Hi,
I have a bicolor blenny which has just laid about 200 eggs on the glass near the heater in my tank.

There were eggs in the same place a couple months ago but I didn't realise what laid them. This time I have seen her going back and forth around the area, so I know who was responsible.

There are no other blennies in the tank so they must be infertile, right? Is it normal for them to do this without a partner?
Thanks

Perfectly normal behavior. I've had fang blennies lay infertile eggs on the front glass of my tank. they'll be eaten within a day or so.

Oh okay, thanks

Half of them are gone now.

Oh shucks when I read the title I thought there would be a picture ...

Is your female almost all black as popular belief would have it?

I thought I had figured it out , thinking the males had a much squarer head , streamers and generally considered more colourful....and females with rounder smaller heads and shorter stouter body ... ( from eye to vent in similar size specimens)

But I'm not sure anymore.

Also There was a thread few years back of someone in Greece who had a very yellow female to throw a wrench in the assumption that we could easily differentiate the sexes with colour pattern.

Do you have clear pictures that you could post by any chance ?

The blenny has a dark purple front with a yellow tail. Don't have many pictures because she spends most of her time hidden in gaps in the rocks. This is the best one I could find. (Yellow tail poking out on the right)
