Now that I know what part of the anatomy it is I'll try to see if I can distinguish any of the juvenile's sexes that way.

I've seen some of the juveniles hang out mainly in shells, especially after getting both of the older multies in there.  When one of the ones from the 46 swims by they act like they're trying to get it to follow them into the shell.  They'll come out, try to get it's attention by kinda nipping at it & as it got closer dart back in.  I noticed a bit of this behavior when it was just the juveniles in the tank but all 6 of them would dart into shells at first so it was really hard to tell. 

I noticed similar behavior in the 46 with the similis & when I noticed fry in one of the shells it used to do that in, I assumed the similis was a female.

I know it sounds goofy to say, but until they get to a certain point of development there's just no telling them apart. And, the more you have in the tank the easier it will be to see general differences in shape and behavior. Cues that seem apparent in a group of 50 may be useless in a group of 6. It's so easy to stop and watch a multi tank for a few minutes every day that soon you will be reading it like a book--it's a drama, a romance, a comedy, and a mystery all in one. :)

As for the comedy.  One of the older multies was doing some digging yesterday.  With some of the mouthfuls of sand he would swim in a circle before spitting it out.  It reminded me of a dog chasing its tail.

I SAW BABIES TONIGHT!!!!!!!!  I'm not sure if they're new ones or the ones from before.  They're still tiny & all eyes but they're swimming outside the shells on my left side of the tank. 

How long is it usually between sets of babies?

Mine seem to go every 5-6 weeks.

Here's a couple pictures.  In the first one you can see both the multi's from the 46 with the juvies.

Good stuff, Olive. :)

Between you and me, it still gives me a grin and bit of excitement to see fresh fry from a shell--won't be long before you're seeing your own fry having fry. Very fun little fish to work with. So glad they have settled in and started giving you dividends on all your hard work and investment.

I think the fry I posted about earlier this month are a second set.  I've seen one fry towards the back left corner of the tank.  The newer fry I posted about are still on the left but a bit more forward.  The few times that the one in the back left corner is out as well as the others there is a noticeable difference in size between them.  They're both still small.

There still seems to be no fry action on the right side of the 2 large Tonna shells.  I'm beginning to wonder if it has to do with current.  The 2 air stones on that side of the tank still have plenty of little air bubbles coming out of them & the output of the canister filter is pointed up & to the right side of the tank.  The left side of the tank's air stone has so much sand on it from the multies digging it's not putting out any air bubbles.

The multies are remodeling so my landmarks of where to look for the two broods are gone.  It's cool that they remodel & all but it's a pain when I'm wanting to keep an eye on the fry.  I haven't been able to locate the second brood & there were at least a half dozen.

The surviving baby is out & about more often.  It's about the size of a month old baby guppy & it's close to 3 months old I think.  If it'll stay out long enough I can try to get a picture.

Well, heck, Olive. I imagine you'll have plenty of fry in time. I have one female that had 4 or 5 spawns and hasn't had any since. This doesn't seem typical. All the other females produce regularly. I can't remember, are there any other fish in the tank that could be turning your multi fry into snacks?

The only other things in the tank are 4 danios, 4 nerite snails & 1 juvenile molly.  The multies don't let the danios or molly near the shell beds.

I noticed a few babies last night.  The left side of the tank has been divided roughly in half with their recent remodeling.  I believe I have at least 2 pairs on that side.  I noticed 3 babies on the right side of the divider (which is a line of shells that are covered in sand) first & then I saw 1 on the left side.  I was wondering, will females protect babies that belong to other females? Or is it more likely that the new baby on the left side is from the pair on that side?  If it's from that pair then its been about 2 months since they've had babies.  This would be the second brood for the couple on the right.  I don't think any of their first brood survived. 

When I had sunspot brevis I knew when they had new broods because I could see the fry in the shell opening before they were swimming outside of it.  The female seemed to use the same shell each time & they didn't constantly remodel.  So far these multi females pick a different shell for each brood & I don't know there are babies until they are swimming outside the shells.  How old are the multi fry by the time they're swimming outside the shell?

There still isn't any fry action on the right side of the tank.  One of the 6 juvenile multies we bought online seems to have been ostracized to the far right of the tank.

The general guide I use is 3 to 4 days to hatch and one week (6-10 days) to leave shell. So week and a half to two weeks post spawning you'll see them outside the shell. Olive, I don't remember where I got that guideline and it may be a mash up of multiple sources.

Now that the old fish have worked out hierarchy with the new fish and all have settled in to their territories, I suspect you'll start seeing more stability. In keeping with their colonial nature, adult multies and juveniles do not eat fry--even if from another female. I've found that the fry hang pretty close to their home shell group for quite awhile. But once they start moving around....I've read reports from people who feel their adult multies have eaten fry, but I think it's pretty much the exception to the rule and there is usually an additional stressor involved.
