I recently put two of my mystery snails together (originally separated between 2 tanks). They spent almost an entire day together "piggy backing" each other. Woke up and feed my fish this morning and found an egg sac on my filter (pictured). I'm worried because snails usually lay eggs right above the water line, and the condensation from the tank keeps them moist.... But this will not happen in the position she laid them. I've propped my hood in a manner that might help, but being that far from the surface, will the babies still drop into the water safely? And I'm concerned about them drying up there. I'm trying to avoid removing them to put them in a "paper towel incubator" because it can do alot of damage. What should I do? Will propping the hood (like pictured) be sufficient? If not, what's the best way to remove it without damaging the eggs?
Sidenote: I moved the female into this tank because she had shell damage due to soft water, and I wanted to get her into harder water for her she'll as quickly as possible without further malnutrition while I slowly increased gh, so fish weren't shocked. It's only been a week and it's showing improvement, but I'm curious if this will negativity effect the baby snails (if they hatch), or if water quality - not mother's health, is what effects their development? I also cannot increase water level because I have babies in a hang off nursery that hangs low, and they'd have no air at the top if I add water.
