1) My sterbai are easily sexed when observed together. The males are visibly smaller than the females.
I do notice a size difference in some compared to others but as I have differnt age groups I find it difficult. I have some which are adults and some which are still young as they were brought to the store from somebody who had bred them and needed somewhere for them to go.

2) I have observed the classic "TEE" formation during fertilization (an observation which you have not posted).

3) ("and this is the real kicker") a female can lay eggs even though a male is not present in the tank.
That is a kicker, lol, however, I saw what I thought was definite spawning behaviour. Two of them were frantically going about the tank together and rubbing on each other. I never saw them locked in the T position but I did see one "nuzzling" the others belly a bit. Perhaps this was it/ I assumed they stayed locked in this position for a while, but if not, and if it's only for a second or 2 then I reckon that I did see it afterall. Whenever one deposited the eggs, she (and she was the bigger of the 2 right enough) went back to the other one and they continued their frantic swimming and rubbing again. I watched only on and off so I assume/hope the T position did happen. It might be silly (no, it is silly) but I felt a bit uncomfortable watching them too intently. They were "loving each other" after all

Also, I saw the same 2 fish at the frantic swimming and rubbing again this morning but had to leave for uni. Is it possible that after only 3 days since the first eggs were laid, another batch will be laid?

Also, although I don't think this will make much difference, if any, my cories are not Sterbai. They are the plain good old bronze variety, or the albino version. I have noticed that the Sterbai cories tend to be larger in general, perhaps this makes it easier to see a size difference?

Jones: I don't take it as having had water thrown on me. I guess I am just very hopeful that I do have a mix and that they do hatch as I would very much love little baby cories swimming about.

...That and I have already bought a smaller tank for the fry to go in once they are too big for the breeding unit, lol, if not, I'm sure I'll find something to put in the new tank. :D

There's about 20 but it's hard to tell exactly because they're so tiny, and move about so much :D

Thanks :D

I fed them Blue's (or I should say Lupin) home made recipe of egg yolk in water then squirt a wee bit at them. I bought some liquifry as well for them to use now but last night when they hatched no fish stores were open obviously so I made do. The home made recipe is probably just as good, but I feel more reassured using the liquifry. I plan to move them onto baby brine shrimp shortly.

They're so tiny! It's hard to believe that a life form that size actually exists. I have to look really hard even to just see them, but when I get them in focus I could watch them for hours - they dart about that breeding unit at top speed!

I'll continue to update this post every day or two with their progress, and to answer any questions anyone has, although if asking questions, please remember that this is my first go at this - I'm doing absolutely everyhitng I can for them but in terms of experience, until now, I have none.

As a little aside - there were eggs laid on the side of the filter as well but I didn't try to remove these as last time I tried removing eggs from a hard surface (the glass) I smashed them Anyway, there are no eggs there anymore so I assume there are also tiny cories swimming about my tank with the other fish, or at least there would have been until they probably got eaten. I have heard people saying though, that you ocassionally get a survivor and one day you just happen to see it in the tank all of a sudden. I will keep a look out for any of these guys, but I'm not hopeful for them.

Well today I noticed the parents spawning again, and this time I did see the T position you were talking about Jones. They have laid most of their eggs on the glass but have saved 5 for the plants. I removed these leaves as last time, and hopefully will have more baby cories in another 3-5 days time :)

I have used a seperate breeding unit for the new eggs however if they keep doing thid, and I have read they can spawn every few days for up to a month, would it harm the babies,. or eggs, to keep them in the same breeding unit? As long as the babies are still really small and wouldn't be able to eat them?

Another observation is that it seems to be a bit of a threesome! I have 8 cories in total but 3 are bronze. The 3 bronze are all displaying spawning behaviour together, though only 2 at a time tieh the T position obviously. However, all three are swimming frantically and all 3 rubbing against each other. Not two at a time, but all three together. I don't know of this is normal but I thought I would post anyway.

The mother also has started to eat the eggs as soon as she lays them, but only on the glass. She leaves the ones on the plants alone.

The second batch of eggs have hatched, only 4 out of the 5 that were on plants hatched but still... :D

Considering there are only a 4-5 days between batches, it's unbelievable to see how much they've grow. The First lot are about 5x bigger than the newly hatched babies.
