Angelfish Eggs

[rocknurworld2006]

My angelfish layed eggs and both are been good parents they layed them on a slate i put in and today theyre are tails sticking out and they were catching the ones falling and putting them back on so have been quite busy . but tonight i looked and thought they had eaten them as they were fine 2hours ago but they were all gone??
then i noticed they have moved them all on a flat piece of amazon sword, why is it they would have done this

They moved them to what they consider a safer place. This is very common.

ok thanks
the other thing i wanted to ask is

1)why do eggs fungus after they have been fertilised on the second day? the 2 previous lot of eggs this happened to this is the first ones to get to this stage, this pair have not bred before apart from these times.

2)can the angels mouth fungus from eating these fungused eggs as the female who previously eat them seems to have a white bottom lip possibly fungus??
thanks

Fungus is believed to be secondary to bacteria where spawning is concerned, I believe this was documented in James Quarles' book on breeding discus. Bacteria grow at a quicker rate, killing the eggs, this is impossible to see with the naked eye. The fungus is secondary, and easy to see, so is assumed to be the problem.

I use pvc pipes in breeding tanks, and rinse them twice weekly under tap water. If I let them sit for a week or more I will experience more fungal problems than if they have been recently cleaned.

The parents are no more or less prone to fungus due to picking off the fungused eggs. Pairs will often lip lock & spar a little, even after pairing. I had a pair long ago that would do this for a few minutes every morning when I turned the light on.

before breeding mines would constantly lip lock for a couple of days .
so do you think this is related to the lip or not and should i treat??
and when u said about the statement about the eggs, is this then a water problem
thanks

I've never treated for this, it is common for breeding pairs who often have a bit of fin, scale, and lip damage due to this. Keeping up on water quality is the best bet with this, I change 50% weekly on pair tanks.

The fungus is probably not a water quality issue as much as the site they spawned on not being clean. It could be a number of other things, many of which are hard to tell without observing the tank.
