Diet of Signigobius biocellatus

[SpektralerSpeer]

Hi everyone,

I am trying to find out what the goby Signigobius biocellatus eats. I have a mated pair in my tank, I watch them sifting through the sand and although they appear to get what they need, I would really like to know exactly what this is! There appears to be very limited information regarding this available on the internet, no-one goes any further than to say 'sand-sifting'. As my sand is full of tiny isopods, I would imagine they eat those. I would however really like to hear from anyone who could enlighten me on this,

thanks,

Paul
