Question on mouth brooders and fry size

[anewbie]

As i mentioned a bit back my a. sp ipiranga finally bred after a year+; for some reason at least by the time i noticed them the frys were a lot larger than other species (such as winkelfleck); is this due to mouth brooding; does the mother somehow feed the frys or just a characterisitic of this species? While the brood was small (10-15); it appears now some weeks later all or nearly all of the frys made it... of course how i will remove them is another issue (complaint?).

Congrats on the fry.
I imagine that mouthbrooding species, don’t get as bit broods as other is just because they need to fit them in the mouth.
I also think that since they don’t have to carry as many eggs, they can “afford” bigger eggs and maybe more pre-developed fry, before free swiming.

But this is all guess work..
