Red Spot Goby - Rhinogobius Rubromaculatus

[cockroach]

They ate the eggs again but are showing signs of prepping to spawn. The female is nicely full of eggs and the male is coloring up. She is a little shier than he is but they are rather outgoing fish. The 4 in my 75gal have even started perching on my hand when I feed.
Female would not come forward.


The male of course has no issues having his picture taken.


This is why they are called red spot gobies.

You will get less egg predation if you use 50mm PVC pipe (or bamboo) slit lengthwise about 150mm long into half circular guards and stuck vertical onto tank walls near corners. Can secure to glass with silicon airline cups or I silicon to dedicated magnetic cleaners for convenience. If eggs are laid elsewhere, the guard can be added soon after but usually they spawn under the guard.

This makes it much easier to guard and predators loose line of sight.

Thanks for the idea. Sounds like a simple fix.

I am actually planning to remove them after the next spawn and leave the eggs in the tank to see if they hatch.

What I have noticed about his pair, I am not sure if it is all red spot rhinogbius or just this pair, is that they like to lay eggs in the open. The tank has pots for caves, gravel in a small container if they want to dig a cave and other sheltered sites but they choose the side of the tank or the airlift tube.

They are in this tank now with all the pots on their sides and stacked to make shelter.
