Angels and Goldfish

The temps are not an issue. Goldfish are fine in tropical temps.

I disagree. Goldfish have shorter life spans in tropical temperatures.

Additionally, angelfish are far faster than fancy goldfish, so feeding would be an issue even if fed the same diet (mine are not fed the same diet).

Mixing these two types of fish, even in a huge tank, would not be a stellar idea imo.
 
Goldfish are from tropical areas in nature, the exact same waters as some of the danios, barbs, etc. from Southeast Asia. They are bred on the same tropical fish farms as our tropical fish. They are naturalized all over the world to the exact same waters as all of our tropical fish, unless you don't count Brazil, Saudi Arabia, etc. as tropical.

Keep in mind that we are only talking about a few degrees in most cases. Room temps usually run 72-74F, tropical fish tanks are usually kept around 78F or so.

There are SOOOO many other issues that effect lifespan that a minor increase in temp will not have a significant impact on lifespan. The effect is nothing compared to the impact the quality of the food and water will have.
 
goldfish are naturaly from those areas but how many "wild" goldfish do you see for sale
NONE

the hobbyists goldfish has been bred to survive in extreme conditions of cold icy water and heavily polluted tanks
that is why they are invading the northern US lakes not the Rio Grande

store goldfish like cold
store angels like warm

we're done here
 
No. Store goldfish are also bred on the exact same fish farms as angelfish. Yes, they are invading tropical areas throughout the U.S. including Florida and Hawaii, and all over the world. No, the ones invading all over the world are not wild type, they are captive fish that have escaped or been released. In fact, many get sick because they go from those tropical farms, to warm wholesalers, to warm fish stores, to air conditioned homes too fast and get stressed when all of a sudden they are kept cooler than they ever have been before.

Can we move past the over-regurgitated myth that goldfish are coldwater and start thinking using facts please?
 
Fancy goldfish are nothing like "wild" goldfish. They do better in cold water. Angels need a warmer tank.
 
Fighting over correct temperature is silly. Everyone agrees these are domestic fish. That means wild temperatures mean nothing. So where exactly does the temperature suggestion people throw out there come from? Do we have exact numbers on how temperature effects goldfish life-spans? Let's keep in mind that natural variation is pretty wide on fish life-spans. It would take quite the research project to prove a statement like "higher temperatures decrease goldfish life-spans!". Are we just assuming that every domestic goldfish out there is supposed to be a coldwater fish no matter where it was bred?



Either way, it's simple. It's a stocking level problem, not a parameters problem.

BTW, parameters are guidelines. Not absolute laws.
 
Again, the ones taking over all over the world are not wild type. They are domestics that were released or escaped.

We should probably call the fish farms and let them know to move all their goldfish to cooler waters because it isn't ideal. We should also let all those goldfish in ponds in Florida to start dying, what were they thinking thriving in tropical temps...

Interesting enough, just about everything thrives in Florida. The list of invasives includes the entire fish store catalog, coldwater or tropical. I'm pretty sure it is physically impossible for a fish to not thrive in the Florida water, no matter what its native environment was like. :rofl:
 
So what are you saying? They can thrive in hot and tropical Florida, but we shouldn't keep them at 80F in our tanks?

Was somewhat of a joke and somewhat of the belief that "proper temperature" is complete bull and fish can and will adapt to whatever they must live in, just like "proper pH" and "proper KH" (which both of those factors people are often told to ignore).

I entirely agree that they can handle the temperature fine.
