In Theory...

[your1stopshop]

In theory shouldn't paradise fish be more suited to unheated, smaller bowls/tanks, than bettas? A betta requires a warmer water temp, while paradise fish do very well in room tempurture, so wouldn't it makes sense because they are related, that a paradise fish would do much better in the environments that most bettas are found in (unheated 1 - 5 gallon tanks/bowls)? I wasn't sure weather to put this under here or the betta section, but since I'm not actually asking a question about betta's I figured here would work nicely. thanks

I'm not 100% percent but i would have to disagree. Betta do well where they are as they are not dependant on filtration as they can breathe air from the surface where as Paradise fish cannot (correct me if I am wrong its just that I have not found any info saying that is does).

Thats the reason I disagree with you.

paradise fish do posses a laborynth organ, and do breath air, I'm am not sure about the extent that they use it. Cooler water can hold more oxygen than warmer water, so the betta may rely more heavily on their laborynth organ than the paradise fish.

Just to note, oxygen levels arent the main reason filtration is used. It's to convert toxic ammonia from the fish into non-toxic nitrate. Bettas are just as dependent on filtration as other fish, it's just that with bettas a lot of people are able to keep up with the water changes to compensate because they keep them in small tanks.

in my opinion, no fish should be kept in a small unfiltered environment. If you cannot keep a fish properly, do not keep a fish at all.

I know what a filter is used for. But the point that I was stressing is that if you put a goldfish in a bowl that had no filtration but did plenty of water changes every day then they would die because there is no surface movement to alow gas exchange. That was my point.

Ah right. I was looking online but I couldn't find anything that said that they did have that feature.

This topic is hypothetical. Please dont ruin this topic with your opinions on something that is not in practice.

 

[Dan Robbins]

Please dont be so quick to incorrectly interpret.
This is my opinion which i am entitled too. I do not beleive that any animal should be kept if not done so under adequate condition. I was not directing my words at him as an individual.
So dont be too quick to ruin this topic by your judgements.

Dissolved gasses in the water will actually be present for many many days, even weeks. If you did that many water changes, the fish would probably die through stress before anything else.

Ah right. I was looking online but I couldn't find anything that said that they did have that feature.

They are anabantids - a group of fish which posess a labarynth organ ( a mass of folded respiratory tissue underneath the gill plates ) this allows them to take air from the surface.

As said, no fish should be housed in an unfiltered environment, so in THEORY water movement isnt a problem, but getting Ammonia out of the water will be.

Im sorry if i've ruined this topic with valid knowledge Reesy.
There are some opinions which im keeping to myself at this point.

 

[Reesy1989]

I'm sorry if i interpreted incorrectly.

And no i guess my knowledge of paradise fish is very limited, i have never kept them and dont intend to. After I read the question I simply looked on wikipedia and it did not mention so as i said before (correct me if I am wrong its just that I have not found any info saying that is does).

I understand you have your own opinion and tbh I agree that just because fish can be kept in them conditions doesn't mean that they should. It didnt come across from my point of view that you had anything valid to say about this theory except that of your opinion.

About the filtration, If you put a goldfish in a bowl of water with no filtration and did a weekly water change then its chance of survival it extremly limited to that of a fish with filtration. To keep a fish without a labarynth organ there needs to be some sort of gas exchange between a weekly water change or it will die?

Thats the point I was making

 

[Dan Robbins]

true, to an extent.
Even with a weekly water change, the amount of waste produced by a fish will probably kill it before oxygen were to run out, or CO2 to accumulate.

Your theory with cooler water is correct.
And they do also have a labyrinth organ.

But paradise fish grow larger and are more active than betta's.

So in fairness, they would do better than a betta in an unheated tank.
They would only do as well as a betta in an unfiltered tank.
But they would not do as well as a betta in a small tank.

Obviously we all appreciate a small unheated and unfiltered bowl is undesirable for anything.
This is just hypothetically.
