Angelfish wigglers on sponge filter

HI everyone! I am new to this site, it looks awesome and I joined today, hope I'm posting in the right spot too. I have had my oldest aquarium for about 5 years now. And just recently, 5m ago, paired off a few of my angelfish. They were becoming very aggressive in community tank. So I'm sure I'll be posting here more but today I have a emergency question!!
My main pair of angels have been laying eggs, getting better at it each week. I'm on round 5 of letting them try to raise there own fry. I believe I am on day 5 maybe 6 this time around and I noticed today good size wigglers prob at least 100 of them, the parents moved them today while I was at work, from the backside of a TerraCota pot to the sponge filter!!!! I MEAN right on the top of it, Iv read a lot about angelfish, raising them, breeding them ect but I have never seen this mentioned, and I am no expert. Is it commen??? Should I do anything? Any info that may be informational would be great!

 

It is very common for angels to move the eggs/wiggler/fry around the tank. I remember the first time it happened with mine, I got all upset because I thought all my wigglers were gone. And it was day 7 when they were just getting ready to swim! Then I found them all tucked into one huge ball of angel fry in the upper corner of the tank...right against the glass. I had covered every inch of that tank with my eyes....never thought to look up there!

But that particular location was odd...and to this day I don't understand it.

But moving them around is very common. Mine usually move them to a different leaf, or the filter intake, or wherever they please. They are just trying to keep them safe

Edit: if all of these little wigglers survive, do you have somewhere to raise them?

 

Wigglers on sponge

HI There, thank you for the response I appreciate it, great information. I am sorry thou I don't think I explained enough about what I am worried about. I have seen them move there eggs and even a few wigglers the last time around: from filter tube to leaf to TerraCota pot. I have seen them put them in there mouth and spit them out to new location or back to location. Last time they only had maybe 10 wigglers and day 5 the dissappeared. They had this set of eggs and its going really well. But I have read that fry can get stuck to even a sponge filter when they first start free swimming. My concern is that the wigglers are directly on the sponge, not the tubing, the parents actually moved them to the top of the sponge filter ????? Has anyone else had this happen? Will the wigglers be able to swim free when ready?? They are close to being ready I think. I couldnt find anything on angelfish putting wigglers directly on an active sponge filter.
I just joined today, so I will update my profile within a few days.. but I currently have 10 freshwater aquariums and 1 Altos (texas salamander) tank. I just cycled a 60 gallontank for angelfish babies for the last 5months (what an experience I'm ready for babies, I just prefer parents to raise them and will give them quite sometime to try Thank u for all the great info!!

 

I'd be willing to bet the parents will move them again...I think it will be fine personally

 

Thank you, I'm thinking ur probably right bc they have been there all day now and look fine and alive.
