I have surprise fry in one of my tanks (I've counted 8 or 9 so far).

I've removed all the adults into a separate tank, so the fry won't be eaten.

I have apple snails in the tank as well. These guys create a lot of waste.

I've removed the filters so that the fry don't get sucked into it. I can't use a sponge filter because the snails eat it. Now I have waste accumulating on the substrate. I don't want to vacuum it, because I don't want to suck the fry out.

I can't remove the fry from the tank to clean, because they're difficult to see and I could not be sure that I got them all.

What other methods are there that I can use to remove the waste?

In my experience with guppy fry, I didn't have any issues vacuuming around them (in a 20 gal planted tank). I just have a simple siphon vacuum and got it running out of the tank, then "paused it" by plugging the outlet tube with my finger, then positioned it in the tank low to the ground and let it flow again. They fry stayed away from my hand and the tube and I just kept it low and had no issues!
