multiple broods in same tank??

[BigJohnW@webtv.net (John Wubbolt)]

Hello All

I wanted to know what were everyones experiences with more than one
brood in the same tank with the parents at the same time. 

Reason i ask is i just siphoned off about 50+ free swimming fry from one
of my pairs of Cacatuoides.   The reason for doing this is that i
already have about a dozen or so 1/4 -3/8 inch long fry hanging out with
mom and pop.   They do a good job hiding up in the thick layer of
watersprite.   After the pair spawned again, i saw mom chasing the older
youngsters and they swam back up into the watersprite where mom couldn't
find them.    I was wondering if i had left the younger fry in the tank,
if mom would have done an adequate job guarding them from older siblings
canabalism.   

I'm glad i did siphon them off because now i have a really large batch
of fry to grow out, but would have liked to have seen what would have
happened if i had left them in the tank.

Any experiences with multiple broods in the same tank will be
appreciated.   Oh i had these guys in a ten gallon tank, bare bottom, pH
of 6.0 and 15 ppm hardness with a temp of 76F.  Figured someone would
have asked the tank parameters so here they are in advance.


Thanks

John W
