Just want to say hi (new to the hobby today)

I know the goldfish is a coldwater fish..............I'll take suggestions for other coldwater fish that are colorful.

Hi Jeep8rus! Welcome to AC, I hope you have a great time participating in the learning that takes place here.

I disagree with the statement that goldfish and bettas are incompatible due to temperature, but I do agree that they are incompatible, because an adult goldfish can and will eat a betta, or just kill it for no aparant reason. Goldfish are not 'coldwater' fish specifically, they are temperate water fish.This means that they can survive in coldwater (even if it's slightly frozen on the surface), and also tropical temperatures (as long as it's a gradual change such as the changing of seasons).

I have a blue goldfish in my tropical community (180g). I also know that there are others on these boards that keep goldfish in their tropical communities. Glimmering Goldfish suggests that the aquarium temp. for goldfish be kept around 74F.

There are a lot of public and private ponds here in SoCal that have goldfish and koi in them, and during the summer, the water reaches 85F easily. But the splash from small fountains or waterfalls aerates the water properly.

Basically, goldfish can thrive in warm water, but they will need more oxygen. As long as you have an extra air stone connected to an air pump, or there is a lot of oxygen injected by your filters outlet, you should be fine. However, your goldfish will need a much larger tank than the 20g. Even feeder goldfish grow very large (around 24" easily).

Maybe you missed it?
 
I disagree with you totally about the compatability issues Socal. Its not a matter of what they can "survive" in its a matter of they should be in. Goldies can live a long time, a 10 year old goldfish is still faily young. I would say 20-25 is a good age for them, they live a LONG TIME.

By keeping them at those warm water temps you dramatically shorten their life spans, its simple, their metabolisms function best in cooler water, by keeping them in warm water the metabolisms go into hyper drive and thus shorten the life span.

Frankly I could care less about what others do that "works" when its blatently wrong and should not be done period. Then advocating that same mindset like you are SoCal is even worse. When we know things should not be done because of actual facts about the effects it has on these animals and we do it anyway its simply wrong. There is a huge difference between fact and actual research about fish and what people have done that works. I would also like to point out that Goldfish can do more than just make it by in "slightly frozen" ponds, they will do just fine in ponds that are completely frozen over with a water temp in the mid 30s during winter. Trust me I know they multiply like rats up here in Vermont in people's ponds.

Again, yes you can keep goldies in warm tropical water, and yes they will survive for a while, is it good for them, no.
 
I think if you got the betta his own small tank, and kept only the goldfish, it would be fine in the 20g. Plus having only one fish will make any moves much easier, and once he gets a little bigger it will be a very nice fish to have alone in the tank. Most of what I have read recommend 20g per goldfish, but if you wanted more/other types of fish, you might consider returning him if that is the case!! Good luck, you can find alot of info and answers to questions on here just by doing searches too, FYI :)

Did you read my post? My whole point, was that the temperature of the water that goldfish "should" be in, is very broad. That's because they are Temperate water fish......not specifically coldwater.

Wait, so if it "works" it shouldn't be done? That doesn't make any logical sense. Goldfish can live in warm water their whole lives, as long as you compensate for their boosted metabolism. It's a very widespread misconception that goldfish are exclusively coldwater fish. So like it or not, this means that YOU are the one advocating a mindset based on false information. I agree that ignoring the facts is bad practice, that's why I'm mentioning that goldfish are not exclusively coldwater fish.

There is a huge difference between fact and actual research about fish and what people have done that works.

Explain that one to me. When someone does research, they test a variable, and it "works". Then it's well on it's way to becoming fact.

By keeping them at those warm water temps you dramatically shorten their life spans, its simple, their metabolisms function best in cooler water, by keeping them in warm water the metabolisms go into hyper drive and thus shorten the life span.

This is just flat out not true. Their metabolisms function at a slower pace in cooler water, than it does in warmer water. Not anymore efficiently or inefficiently. It's because of that fact, that they are able to thrive in temperate conditions. An increased metabolism will not shorten their lives in the correct conditions. What are the correct conditions? Warmer water, more oxygen, more food.

Peace
 
Thanks for all the input, I'm really glad this board is so active. And, yes, I had missed the reply by SoCal.

Well, I would like to set up a community tank and keep my fish that I currently have.

I'm going to look at getting a separate tank set up for the betta and maybe have it become the community tank? For now, the water is 74 so the betta should be fine?

For the goldfish, he's actually 2 1/2" right now. So for those in the know, how long does it take for them to mature to full size? He's a calico ryukin.

I cycled out 20% of the water today. Do you pretreat your tap water? I pretreated the tap water when I first filled the tank, and I also just added "cycle", a bateria supplement, to the tank to make it easier on the fish.

What's a good bottom-feeder that's compatible with goldfish?

Thanks,
-Russ

The betta will be fine for now, and will be just fine in it's new home. (you're going to fishless cycle it first, I'm guessing?)

The goldfish will take a few years to get to it's adult size, but it depends on the temperature, how much you feed it, etc....

If you change your water by bucket, then yes, I would pretreat the water while it's in the bucket. If you're using a python or Lee's gravel vac (same thing, just that it's blue and less expensive) then just treat the water as it pours into your tank.

If your tank is still cycling, I would do larger daily water changes. 50% + maybe even twice a day. From what I've read (testimony from others on these boards) the product "cycle" doesn't work. While "BioSpira" on the other hand, does. I always seed my new tanks with lots of filter media from my other tanks, so I don't have experience with either product.

Dojo loaches (aka weather loaches) are compatible with goldfish, and are very active.

Your betta minght appreciate a temp of around 78-80 degrees, ultimately. that is where mine is most active. you do what you can...he will be fine in 74, but more active a little warmer.

I think whatyou are encountering with temp is ranges that fish can exist in. Now that you have settled who you are keeping and where, you can find books specific to those species, and create an appropriate habitat.

If only we could ask the fish, then we'd know what was good. Any one a pet psychic?
