It's not OK to have goldfish in a tropical tank. This info should help you find out how to care for them: http://www.myfishtank.net/forum/showthread.php?t=28247

I believe you have an oranda goldfish, which is a breed that has a crest on its head.

The ones with the mass on the head are orandas, but bred for that mass and are called lionheads. Nice fish, but as lotus said should not be kept with tropicals.
