Suspected egg in tank

[Shan98]

Hi, new to fish keeping literally only had fish for a week and I already have so much going on. In the tank I have 2 x Cory catfish, 8 x pacific blue-eyes (1-2cm fish), 6 x male guppies, 6 x female guppies, 6 x neon tetra, 1 x male gourami and 1 x snail. This is in a 100L tank. They all seem happy and all group together.

Last night I was watching the tank and seen what I thought was a baby fish. Couldn’t find it again, but this morning I found 2, what I think are guppy fry. I removed and put in a container with holes and stuck inside the tank (attached to tank). While looking for other suspected guppy fry, I found what appears to be a jelly like ball in my fake plant in the tank, I also have 2 live plants. The egg is a greyish-beige colour and when looking closely it has a little brownish coloured spot inside. Is this an egg? If so is it a catfish egg? Why would there only be 1, is it possible other fish have eaten the remainder? I have put the fake plant in with the 2 fry. Any advice helpful.

It doesn't look like the typical cory egg to me. I can't rule out that those aren't cory fry though. The picture isn't super clear but they do resemble cory fry that are a couple of weeks old. If that's an egg it's not from the same batch that produced those fry.

Here is a more clear picture of the fry (top right corner). I assumed these were guppies purely as we had/have 4 x pregnant female guppies at the moment.
If it’s not an egg, is it an algae? Should I remove it? Here’s a couple more pics of it. Appears really sticky and quite round. Neon tetras I thought have quite small eggs, and I am unsure about the pacific blue eye as there is very limited information on these. We have only had the catfish since Monday just gone.

Oh ok those aren't cory fry. You're probably correct that they are guppies. I honestly have no idea what that egg vs fungus thing is. Just that it's not a cory egg. Maybe someone else will be able to shed some light.

Thank you! Hoping someone else can shed some light on this mysterious ball/egg…. I’ve done endless research with no further insight!
