Mama Discus fighting Dad w/ Fry

[preswash]

Iv'e got a pair of turquoise that have raised 1 group of about 50 fry. Dad did most of grazing the work. That batch of  fry are doing fine in a grow out tank. The next spawn was partially fungus-ed with a few wigglers. They moved the wigglers but they were gone the next day.  Now here's the question. On the next spawn, the current spawn, they got mostly wigglers, about a hundred. Then the fry were grazing mostly on dad for a day or so BUT MOM STARTED TO GET VERY VIOLENT WITH DAD... ramming lip locks causing the fry to scatter.. the fry would find their way back ... mostly to dad cause mom would shake them off.... now today the fry are gone.

Raised first spawn, amazing. Second spawn partially fungused and a few wigglers, they moved wigglers then gone next day. Third spawn of about a hundred became grazers then mama got violet on second day of grazing. Third day fry gone

There are some times that one parent will not want any part of raising the fry. There is a possibility that she is ready to spawn again and is trying to get the male to spawn. My suggestion is to get something you can slide into the tank and make a barrier to divide the tank, some plastic mesh or whatever. After they spawn and the fry are at the wriggler stage, divide the dad and fry off separate from the mom. You could also just take her out of the tank and put her in a separate tank, if you have the space.

Fourth spawn got to wigglers then gone.   Fifth spawn mom and dad fanned eggs to wigglers.. removed mom... dad still fanning wigglers now.
