So I was finaly able to get a good pic because a egg sac appeared on a rock I am selling I just noticed it a few days ago. I Have had these sacs since I got the 75g tank and the fish from the person I bought from. The fish that were in the tank before I got it when their were egg sacs before are. I think they are from the chromis fish but not sure. Can not find any pictures online of the egg sacks.
2 chromis
1 foxface lo
1 clownfish
1 yellow and pink dottyback
I have in the tank all of the above plus
1 ywg
1 pink square anthias female
1 4 stripe damsel
3 clownfish
1 lawnmower blenny
1 6 line wrasse
1 green spot mandarin

Not sure which thing were looking at but if it’s the black/dark mass twards the bottom that looks like that black sponge I’ve seen before.[/quote]The would be the openings on the bottom of the over flow. No black sponges in my tank but I do have a huge orage sponge growing on a rock thats getting bigger.

you sure it’s an egg sac and not just a sponge or a flatworm ?[/quote]I would not think this as a sponge as I have seen them many times appear and when they do it is over night not something that starts off small and grows. It is a sac of some sort that is attached to my rocks by thread looking stuff. It is fairly strong to how it attaches.
they just appear this 1 is a smaller one half a dime size. I have seen some that had more strands connecting them to the rock. They are only in my main tank never in any other tank.
You might be right. I searched white sponge look like egg sac and came up with other people with them calling it a sponge. They refer to it as looking like a spider egg sac
