Thanks sharptooth, guess I'll have to give it a try to find out. My marbled is only 8" and pretty calm unless the pike cichlid or catfish goes in it's cave. Then it'll snap and push them out.
I didn't know they were more of a filter feeder. Thanks guess you learn something new everyday.

After about 2 years i finally have male male MARBLE GOBY back in what i consider breeding shape. Also my female is solo in her tank, so after a water change i think it will be a good time to breed them again. Going to do things a little different this time i plan to breed them in the females tank then put the male back in his tank. Im thinking of hatching the eggs in a 40 breeder or 55 gallon haven decided yet.
heres my female showing off her camo, tanks are set up so they really blend in for hunting.


Very stunning! Have you bred them before?
