No reference with respect to size but gives idea of general appearance of eggs (actually embryos once fertilized). These eggs from CNBG of the Manatee River Drainage. The parents of the eggs have never been outside the lab.




Below is a video showing the father of the brood above fanning. Fanning is energetically demanding. You tell a male is fanning because pushes forward with tail as pushing back with the pectoral fins. The male will often turn on the nest moving water over different points in turn.



He will tolerate other large males in vicinity of nest but will not tolerate smaller fish or females. Both are prone to be predators on embryos and prolarvae.

Typically males do not feed while tending brood.
