Betta & Koi & Goldfish?

[IHave2Goldfish]

Will they mix? Ive got the temp at 72.
Will they fight?

 

[Styx]

I would think there would be problems.

 

[consp]

koi can grow to 1m in length so theres your first problem.

keep bettas on their own they do better.

if you want something new for your goldfish buy either a comet or shubunkin (unless your goldfish is fancy). If your goldfish is fancy ONLY keep it with other fancies... otherwise the other slender fish will get the food faaster and your fancy will starve.

I'm sorry, you've asked this in Chit Chat, and we told you the same thing. No, won't work, don't do it. Bettas and Goldfish, and Koi (where did you get the koi?), will not go together and thrive. Just find a better home for your goldfish (like something over 40 gallons), and keep your betta at a warmer temperature, like 77-80 degrees. All your fish will thank you for it. Koi in an aquarium is an issue under debate. There are those that feel that some smaller varieties can be kept in very large aquaria. We're talking over 100+ gallons for one fish. On the other side are people that believe that koi are only suited for ponds. At any rate, a normal koi will not do well in a 10g aquarium, period. These fish can grow to an astounding 4ft long, and I have seen such fish at zoos.

Yeah, koi are messy fish too!

Keeping them in aquariums rather than ponds, where conditions are 95% much better (as they are more regulated) they will grow super fast!

Never put a comet in with a betta. I did it once. Big mistake. The betta literally chased the comet around and tossed him about like a shark.

How many times are you going to ask this? C'mon... you should know by now that the answer is still no.

The Common Goldfish is a type of carp. These hardy fish have been bred and kept in ponds and aquariums for centuries in Asia. They have an average life span of about 10 years. When goldfish return to the wild, they revert to their natural colors (green to black) in just a few generations.

These are some pictures I took of some wild carp at Ten Killer Damn, these are basically wild, common "goldfish".

Still think that'd be ok in your 10, 20, 30 gallon aquarium...lol or with your betta?

Although it is very difficult to kill a Goldfish through mistreatment, it is equally or more difficult to have your Goldfish thrive. They have several peculiarities that make them incompatible with ther fish. One big mistake that people often make is to keep goldfish in a tropical tank. Goldfish ARE NOT TROPICAL FISH!! If you put a Goldfish into a tropical tank, you are mistreating the Gold fish and your tropical fish.

No way, they aqre two completely different fish. Koi and goldfish are coldwater fish and betta are tropical fish. Putting those together is just asking for trouble.

My sister in-law did this and the betta ended up get a bacterial/fungus infection and die. So it's up to you if you want a dead fish.

fighting is the least of your worries when it comes to housing such incompatible fish together. here are just a few of the other reasons:

1) goldfish grow HUGE. i've been told by experienced goldfish keepers that if your fish is not growing about 4 inches per year initially, something is wrong.

2) goldfish are very messy. they don't have stomachs, and have very inefficient gills. they produce huge quantities of ammonia that can easily harm the delicate fins of fish like bettas.

3) 72 is on the cool side for a betta, while goldfish need the colder water because it has a higher dissolved oxygen content. inefficient gills, remember?

4) goldfish require extensive filtration to keep healthy. bettas don't do well with a strong current.

5) coldwater fish (goldfish) and tropical fish (bettas) have rather different dietary requirements. goldfish should not be eating tropical fish food, and vice versa. this is difficult to avoid when they share a tank,but unhealthy for both fish.

we have already been through this here

i really think you are just trying to get us going

Ok I'm gonna say this.....it depends on the VARIETY/TYPE of goldfish on what water temp it needs...some are fine and dandy up to 90 degrees F. I mean, they do have varieties that live in ponds that are outside in the summer time (like at zoos) and the water gets well over 80 degrees and they don't die.

So that is a Nil argument unless you are talking about certain varieties of goldfish which do better in 72 degree or colder water (which several types do, not ALL can tolerate the warmer water temps).

The temp of the water really has nothing to do with them breathing..the surface area does. That's why they always tell you if you are going to keep them in a bowl to only fill it half way, so there is more surface area for more oxygen intake for the water.

Warmer water isn't going to make them poop or produce more ammonia either..feeding them too much will, and not getting uneaten food out will; as well as not providing enough filtration, the proper type filtration, or frequent water changes.

What argument you need to focus on is the fact that #1. they are not tropical fish and #2. their bodies produce different chemicals and different amounts of chemicals then tropical fish do.

They do have different nutritional requirements, but they aren't "that" different from bettas...that isn't the REAL concern though (bettas don't eat flakes anyways...and if you feed a live diet it's basically the same diet).

The major nutritional fact you need to consider is, that alot of the varieties of goldfish can't swim fast so a betta would eat most of the food before they got enough..so they would not be getting proper nutrition. And the betta would be eating too much. Both of these factors can harm both fish at the same time.

That being said, goldfish do produce unusually large amounts of ammonia, and other bi-chemicals. This in itself should discourage you from putting the 2 together. But also consider that Goldfish, just like bettas, can and will be very aggressive and chase/nip/kill other fish..they do it to each other..why not a smaller fish? Most goldfish (unless you are buying feeders) are already as big or bigger then a betta.

Also consider, that your betta may tolerate the goldfish for a while (or vice versa), but once one of them crosses a line the other one may start to harass it..causing it stress..which will lead to it getting sick and cause it to either die or become very ill and require large amounts of $$$ to get it better (goldfish are not cheap where I live, unless you are buying feeders. Even the smaller ones start at $10 here).

Why take these risks?

Why do you think when you go to the Pet store or Wal-Mart that they have the fish segregated away from the tropical fish? Same with saltwater fish.

Because they aren't meant to co-habitate with each other. They are completely different species, from completely different areas of the world, and require completely different care and nutritional values.

If you want saltwater fish..you need to learn how to better care for fish in general....or you are going to end up with a tank full of dead, expensive fish...real quick.

You can't be selfish, greedy, or irrational when trying to care for fish. It's not fair to the fish, and it's not fair to us for you to come on telling us all the idiotic things you are going to do..knowing we will try to talk you out of it.

It's cruel and unusual for all parties concerned. Either take the advice, or don't even tell us about it (since you obviously weren't going to take the advice in the first place).

Hopefully though, someone that is logical/caring will see this post, and not make a bad decision that they might have been considering. Hopefully this information will not go to waste and will not have been in vain.

Ok. You are really angering me. You've asked this many times. Stop asking until you get the answer you want. You won't get it. You will murder your fish.

Get a bigger tank for your goldfish. They are in inadequate conditions. You need 20 gallons per fish. You have 10 for two fish. This is an animal that will live to be upwards of 20-30 years old and grow to at least 10 inches, often more. Do what is right by the fish you have, and do not even consider going Koi unless you've spent tons of time researching pond size, care, management, etc. Considering you refuse to research what the fish you allready have need, you should not get Koi, or any other fish, until you are SERIOUS about their proper care and husbandry.

Your betta should not be kept with any fish to make it simple for you. They are an agressive solitary species that prefers spaces smaller than most social fish are able to kept in. Get a nice 2.5-10 gallon tank and keep him alone in temps of 74-82 degrees with mild filtration. He will live several years and be a happy camper, and will not ever need other fish.

Koi simply should not be kept inside. They get to be a good 3-4 feet long and need other Koi for company, so ponds are the only realistic option unless you have the money, time, and expertise to get an aquarium that is hundreds of gallons in capacity. You are 14. Please just care for your to goldfish and betta properly. You can get Koi when you have a place of your own with a nice, big pond in it.

Coldwater fish can not and should not be kept with tropicals. Bettas should not be kept with much of anything. Goldfish are heavy waste producers and fin nippers, both of which would hurt your betta. They have entirely different space, filtration, dietary, and social needs. They are incompatible species.

Now, would you please either do what is right for your fish, or just stop asking us to get involved and care, then do whatever you want anyways? If you really want to keep your goldfish in an undersized tank with a fish they will kill, fine, but in the end, you're going to be changing your screen name to "Ihavenolivingfish."

i'm going to have to disagree there. the warmer the water, the less dissolved oxygen will be available.
