For four days I am raising once again a clutch of Rhinogobius leavelli. Unfortunately, I had removed the clutch two days early and was beginning to think nothing will come.
But .... The larvae are incredibly stable this time, and after 4 days are still living about 1500. I'm curious, how many are still there in 6 days, because they all eat very well and I have a great culture of freshwater Brachionus at this moment . But more than 100 I will probably not be able to raise.

Today while feeding....

It's more of an estimate, Jim. The clutch was about 8000 eggs (2 females). A clutch I really counted (stamped) and the subsequent clutches were still larger.

Yes, today the bellies are round at last. Yesterday I thought, the most of them would not like to eat... but sometimes they need a little more longer time.

Amazing, is that quantity of eggs typical of Rhinogobius Jutta?

Only for the pelagic species, Matt. The bento pelagic species have between 40 - 100 eggs.

That makes sense, thanks. Was wondering how a male could care for so many!

Matt, the Male (his Name is "Scarface *g*) is an old man with a widish head. He takes some places for breeding, where he mustn't do very much, e.g. this flower pot trivet. There he must only rotate and wag a little bit with his dorsale fins :-) And the eggs are very, very small (2 mm long and 0,5 mm Ø)
