Longfin Albino Brisstlenose Pleco bred...i think..need help

[Romania4eva]

ok so this summer i updated my pond to a 125 gallon pond. put in a few 25cent goldfish and 3 koi about 5 inches each. then i went and bought 2 small longfin brisstlenose plecos, who grew over the summer and i had one male and one female. since i live in illinois, i had to move them to a 10 gallon tank inside for the winter. my goldfish bred too, resulting in one baby goldfish, who grew like crazy in the month and a half he was in the 10. so i have 2 plecos, one goldfish, and 10 or less ghost shrimp in my tank. i noticed my pleco built a cave under a rock and was always there. never checked waht he was doing, just heard him digging in the gravel at night (kind of annoying). today after feeding my fish, i realized he isnt deep in the cave only at the mouth of it. then i looked at my goldfish and it looked like he was choking. in his mouth was something white. he spit it out party and i saw 30 or so egg shells all united together in a bloob...most were clear and split in half,a few were yellow and one was orange barely see through. they are about the zise of this O. i then lifted the rock and didnt see anyting elsee there, beside a larva dragonfly which i squished cuz it can eat baby fish. i took the blob of eggs and put them in a little cup floating in the tank. the goldfish is going in the pond tommorow. im gonna float him for an hour or so and hope he doesnt die from the shock, but i personally dont care too much now that he did waht he did. my questions are the following

-waht are the eggs from? the plecos. if uve breed them before waht do yellow or orange eggs mean.
-how long till they hatch if ever.
-what temp should the tank b at.
-are the shrimp or plecos a danger to the eggs if i let them on the gravel floor of the tank.
-will the eggs hatch in a cup that has no circulation? if i change the water a few times a day.
-and anything else u might have to say that could help me.
