I have kribs, gouramis, Ram and firemouth so it would look stupid
Regardless of "looks", this hardly qualifies as the "average", fairly peaceful tropical community tank. Tthese fish are mildly to quite aggressive, and would at best nip the fins of the slower goldfish and at worst kill them. Some of the more peaceful tropicals like livebearers or tetras can, as regards
temper, get along OK with goldfish.
That said,
DON'T DO IT.
Tropicals are
enviornmentally incompatable in nearly every way with goldfish.
Goldfish are:
- coldwater fish that like a
- high PH and a
- diet very rich in plant matter
Most community tropical fish like
- a PH closer to neutral
- water between 5 and 15 degrees warmer and
- a (generally) higher protien diet
If you put tropicals in a tank properly set up for goldfish, they will likely die very quickly. If the cold water or the high PH don't kill them, the excessive waste production by the digestively inefficient goldfish will.
Goldfish put in a tropical tank seem to survive a little better, but they SURVIVE, not thrive. They still have stunted growth, shortened lifespans, higher disease rate, more different diseases, and other, less easy to pinpoint, ailments where they just don't do "right". Basic tropical flake is too high in protein for most goldfish, and can lead to severe constipation issues, which over time can also lead to other illness. The higher temperature weakens their immune systems. The lower PH lowers their resistance to parasites and infections.
For the proper, humane care of both types of fish, do NOT mix goldfish (or other coldwater fish) and tropicals.
