Goldfish

  • We are currently upgrading MFK. thanks! -neo
Goldfish are cold/temperate water speies. Their water should be kept at 55-65 degrees. Plecos are tropical and should have water 73-78 degrees. Plecos and gold fish should not be housed together for that reason. One fish is going to be stress by the temp of the tank no matter what.

Common plecos grow to be between 16 and 24" depending on the species. They have no business being housed in a 55 gallon tank, no matter what the temperature.

Ya ty. I only got him because i never had a pleco. Im not a fan of them.


Well thats ok they are not absolutely necessary. You can clean any algae off the glass by hand. That being said I would just trade it in or give it some one that can use it and not bother getting another one.
 
I was told goldfish should be housed 55-75degrees. I have the tank at 71. Had him for years with no problem

Yes golfish will do fine at that temp. Some people like to qoute the "book". I have tons of goldfish in my pond. In the summer time the pond reaches the mid 70's and goldfish are just fine.

Survive and thrive are two very different concepts. Yes goldfish will survive in water that warm. They will survive water into the 80's for short time periods as well. You said your pond reaches the 70's you didn't say it it stays there for 10 years at a time. Big difference.

For goldfish to thrive, they need water much cooler. The enzymes associated with the digestion and assimilation of their food function best at colder temperatures. White blood cell production drops off sharply at temperatures over 24 degrees C reducing immune system function substantially. Liver enzymes stop functioning properly and reproduction is largely prevented entirely due to suppression of hormone production.

Yes the fish will survive at 75, but life span is greatly reduced (typically by more than 1/2) and so is quality of life.

It would be my pleasure to provide sources of information from scientific literature to back any of this up should you want them.

Goldfish should live 25-30 years. Keeping one for 5-6 means you have kept it alive for about 20% of its lifespan. You still have a log ways to go.
 
"Temperatures for goldfish are a surprisingly complex issue. Goldfish are technically cold-water fish. However, just because goldfish can survive a wide range of temperatures does not mean they are healthy or happy at those temperatures.

Goldfish in the wild, so to speak, can survive temperature ranges of forty to one hundred six degrees. The extremes will kill goldfish if the exposure lasts for long.

The optimum temperature range is sixty-eight to seventy-five degrees. Some breeds prefer slightly warmer temperatures.

Sudden changes of temperatures can be fatal, even within the ranges given above. While the classic method to deal with this is to spend twenty minutes or so of slow immersion time to equalize the temperatures. For extreme situations such as purchasing a goldfish in a store at seventy degrees to place in a pond when the outdoors temperature is forty, it may take days or weeks of careful preparation to avoid a high chance of death. "

"While goldfish don't like temperatures over 75°F (24°C), they do seem to like seasonal variations where the temperature falls to the high 50s or 60s (15-20°c) in the winter. Fancier goldfish are an exception and cannot easily tolerate temperatures below about 60°F (16°c)."

We are not talking about common goldfish. We are talking about Oranda and fantail goldfish. These goldfish perfer thier water temp to not drop below 60 f nor above 75 f. Seening how this persons water is 71 then this persons water is just fine for fanny goldfish. Not all goldfish do well in the cold temp waters that you say they do.
