Can a gold fish live with these fish?

I don't suggest it, if your don't water temp mumbo jumbo, they also poo a lot, the goldfish compared to tropicals. that can hurt your bio load ( I think thats what it's called) and can hurt your fish. But if you truly need to, it will work just as long as they aren't overall aggressive. Though Big fish have a tendency to eat little fish, so get "clumsier" goldfish, not like comets/feeders which are fast and will eat the tropics. I've done it before with guppies and a black moor ( I was switch from goldfish to tropicals and that moor just won't die so I had to keep him) It worked the moor died with a year don't know if that was because of the tropics
