angelfish eggs and water changes

[angelsfirst]

Hi,
I have a pair of angels that are spawning. The eggs seem to get to the stage of wigglers and then they are gone. Can I do water changes while the eggs are still on the slate? I leave the parents with them. This is the 4th spawn and no luck. I perform water changes before they spawn and then usually wait until the wigglers are free swimming. Do I need to perform more water changes inbetween? Thanks for your help,

yes, you can. I would keep them small (25%), and don't let the water drop so low that the eggs are out of water (common sense). Sounds like their getting close to "getting it right". Maybe the next spawn.

What other fish are in the tank? I imagine any bottom dweller would desimate an angel spawn as they aren't the most agile fish in the tank.
