I think the eggs are about to hatch. What troubles me is the amount of fungus of the infertile eggs. The fungus covers the good eggs. I can't take the infertile eggs away cause I would damage the good eggs too as it is almost impossible to reach the eggs in the tube and see what you're doing. So what is best? Keep waiting and hoping there will be enough fry that hatch before the fungus takes them?
Here you can see the fungus between the eggs (I did took some away but not enough I'm afraid)
I think the fry is well developed in the egg and about to hatch?
Hi Hans. Do you have an airline going through the tube, with bubbles, to aerate and stimulate the eggs? This really cuts down on the fungus issue.
I also use a curved eye dropper/glass pipette to suck the fungused eggs out. I do occasionally get a good egg in there, but I just put it into the end cap and make sure they get aerated too.
Here's a pic of the eye dropper with some eggs I sucked out. I am unable to really get at the eggs with a straight one. Even if you do get a few good eggs with the bad, it's better than if you leave the bad ones, as the fungus will take them over anyway, and it can spread FAST. In this picture, you can see an opaque egg, and a good, clear fertile egg. I suck them out and put them in a little bowl. When I'm done, I look through and pick out the healthy looking ones and put them into the end cap as I said.
Here's a short clip of a couple eggs I accidentally removed with bad ones and put back in the tank. You can see one of them wiggle, getting ready to hatch. This morning, they had hatched, and are out and about in the tank somewhere, haven't seen them, just the remains of the eggs are left in the cap.
Thanks Lori. Indeed I have an airline going through the tube, rather strong in fact. But I think the problem is solved now, because the fry is hatching at the moment. Just in time I suppose. That curved eye dropper is a fantastic idee, I have only a straight one with which I collect eggs and fry with other species. I couldn't get in the tube with that eye dropper. Let's see if I can get a curved one somewhere.
What did you feed the fry the first few days? I have Liquifry (some sort of liquid food with tiny little particles). Brine shrimps are also ready. I reckon they feed from that thick belly first.

Good! Glad you are having success!
I feed vinegar eels, walter, banana, and microworms; (depending on which cultures I have) and baby brine shrimp. I also grind up fish food into a powder. And I really like decapsulated brine shrimp eggs.
I have micro worms and vinegar eels too, so that won't be a problem then. They are - like there parents - not the most active fish (well, when you're used to rainbows, which fish is?). They just lie on the bottom with minimal movements.

They do hang out and not do much when they 1st hatch. But mine were very active, especially in the afternoon sun--they would dance and be at all levels of the aquarium, perching on plants and rocks. They were also pretty interactive, always excited and coming to the front of the tank, or hanging out watching people in the room. I love gobies and gudgeons because they are little "watchers", always curious about what's going on outside their environment.
