Thoracochromis brauschi spawn

[chriscoli]

I stripped two holding female Thoracochromis brauschi (Lac Fwa Bloodthroats) on July 29th, eggs from both looked like they were developmentally the same so I put them both in the same tumbler together.

I had been keeping the group in regular, dechlorinated tap water. This was the group I got from Esther not too long ago.

I was amazed at how many eggs each female was holding.

Fry in a basket eating crushed flakes now.

Congrats on the spawn. It looks like the young are off to a great start.

Woooohoooo! Congrats! Glad to see they are doing their thing.
You might soon be over run with babies as they were very prolific breeders.
I still miss the big guy. Is he the daddy?
Do you have pics of their tank? Just curious what you have done.

Well done, Christine!

What's your set-up for them? I found mine to be pretty rough on each other.

Awesome job Christine!

Like Matt, mine beat up on each other pretty bad. But I still miss them.

Big daddy is in a quarantine tank being treated for an infection. My suspicion is that he got too stressed after spawning with his girls and furiously defending his territory. So he's in time-out for the moment. I originally had them in with a mix of cichlids in the 100 gallon tank, but they've been moved to a 75 with some mbuna.

Esther, what pH did you keep them at? I've read that the pH from their natural water is high, but in captivity, male-heavy broods are observed at high pH.

Congrats!

Congrats! They are pretty fish

I'd say my pH was somewhere in the 7.4-7.6 range.
I was never able to determine the M to F ratio on the numerous spawns I had, although I suspect they were male-heavy. I always tried to keep the smallest of a batch in reserve in the hopes that they might turn out to be F. Worked a few times.
I never had the space to do a study on pH vs. sex of fry and never read anything that gave a definite answer to that question...

the fry look great, you've got your hands full there.

Looks like a bunch, how many?? Just sort of wondering if there is a usual (or max) number of fry from mouth brooders. I have seen 26 from one females mbuna. Such a small mouth seemingly.

My T. brauschi females (not even adult sized yet) routinely spit out 50+ fry.

 

[chriscoli]

I'd say they probably each spit 40+

 

[dogofwar]

I've had 1-1.5" females Vics (I know there aren't Vics ) spit upwards of 30 fry... and some of the larger Barombi-Mbo fish spit < 20 for 5" mature fish... and female Mossambique Tilapia at 5-6" spit several hundred.
