Answer 1

Don't get that many fish. That is way too much for a pond that small. Get 8 goldfish. You can probably add more goldfish, but not koi and not the rest of them.
A plecostomus (sucker fish) will eat fish eggs that it comes across, yes. Frankly, plecos cause more dirt than they clean - they don't really clean a fishtank, they just eat fish good and a bit of algae, and they are poop machines. Don't get a pleco for your pond.

Answer 2

Absolutely, that sucker fish (plecos-algae eater family) will harm any eggs of any fish. These fish just don't feed on algae, they feed on left over food and pretty much anything that's on the bottom of the tank. They can get more in their mouth than just algae. First hand experience! They really haven't been known to attack other fish unless threatened (rare), but it has been documented that these (plecos) fish have chased down and somehow kill other fish that are smaller. I don't know how. I guess suck them to death. LOL. If your parent fish are on the guard (which most are), things might be safe for the eggs.

Answer 3

do not get that much fish dude. you should do it slow so you do not mess up.
