I posted a thread in the goldfish discussion forum asking about the compatability of South American Dragonfish (Violet Gobies) and goldfishies. Well nobody seemed to know so after a while of searching I came across this:
http://www.aquariumfish.net/catalog_pages/...dragon_fish.htmThe dragonfish ARE compatable and are only aggressive to others of its own kind. Although, don't put them in with smaller goldies, as they might think it is food

The eyesight of the dragonfish is somewhat poor and it's main food is live blackworms and ghostshrimp.
Just for everyone's information

I think they are beautiful fish and may get one when I get a bigger tank.
