Don't remember these fish years ago?
There's a large aquarium which I enjoy , while visiting a local walk-in clinic and I especially enjoy these gold fish, though I don't remember ever seeing them in any aquarium store I've ever visited. They're about four inches long tops and don't seem to have grown much for the past couple of years, so they may be about their maximum adult or mature size. I love the color , but they're sort of stocky and that bump over their heads is sort of interesting. They don't seem very agressive , though I have a suspicion they're a chiclid, and there are also a couple of good sized Severums in the tank with them. Anyway, I guess I'd remember them , when I get my new aquarium, should I find them in any local store , but they may not be that easy to find?? I've seen Gold Severums pictured on a couple of web-sites and they're somewhat similar, but I don't recall seeing the head bump on those, and it's possible they're a cross between the Gold Severums and another chiclid??
