i thought, 2gal was ok, 3-4 is better, 5 is excellent??
is this going to be one thing that ALWAYS gets contradicted??
Yup always will be!
A dog can survive in a small crate for many years, but no one sane thinks it ok to keep a dog in such a manner.
Many people train there dogs with a crate, and leave them in it while at work!
Your dog pound does the same thing!
A human being can survive in a small room for life , should they? No of course not.
They do this with phycho people, put them in a phyc hospital and lock them up in a rubber room for days even months without a window to see daylight
The reason I advise to keep bettas in 5 gals + is because they do require swimming space like any other fish. 2 gals is not enough space to really swim ( and they certainly can) and adding the nessescary filters and heaters cuts the swimming space even more.
Filter takes up next to nothing depending what you go with many corner filters work well, usually seen in breeding tanks just like sponge filters. I disagree to the swimming part although would depend on dementions of the tank. I have seen 1gal holding tanks with plenty of room for swimming, its not how tall it is but rather how long it is for them especially when they make bubble nests. As for a begginer I would recommend a bigger tank only for the simple reason its easier to maintain.
When people remove filters in particular for that reason ( and if the filter they have chosen is too strong ) , they are giving a greater risk of rendering their tank's biological and chemical environment unstable. Plus they make more work for themselves because they then have to do large very frequent water changes which are well known to be stressful for many bettas.
nothing beats water changes daily, how do you think breeders are able to actually breed bettas in a tank that is not cycled and has no filter?
Tiny tanks are just completely illogical and pointless for keeping fish in due to the above reasons . It's common sense.
I would think this over again I have seen betta walls that are successful in raising fry to show quality and each has its own container of .5gal, its the perfect setting for keeping water maintained cycled and heated, sucks when 1 fish gets sick you need to treat them all as they share the same water. For people to breed bettas would you tell them its better to go with a seperate 5gal tank for ea betta, I bet they would tell you that you are crazy!
Besides, the average house, flat, apartment ect DOES have room for a 5 gallon tank. Most actually have room for a 10 gal with careful arranging.
I use to live in apartments always on the main floor where its cement and the foundation is cement, in one place I had a 5gal tank wasn't allowed anything higher than that, at another place wasn't allowed anything above 55gal, at another place wasn't allowed any animals at all fish included, still snuck a 2gal tank into my bedroom lol.
I like to see fish swim naturally and in enough space to be able to do so. I don't believe in using bettas as desk ornaments by keeping them in little 2 gallon tubs that can't support them properly or give them enough room.
I don't believe they should be desk ornaments neither! Its fun to watch them swim naturally but some might overdue the tank size see below. A 2 gallon depending on if it has good square footage not up and down from side to side i mean is fine, depending if you want to do frequent water changes and smaller the tank the harder to maintain water quality!
((Look at the hobby this way keeping fish is not about keeping fish(Learn to keep water its more important))
I will never agree with keeping them in anything smaller than 5 gals on a permanent basis, nor will I ever suggest anyone do so. There's no need for it.
I will never agree with with keeping them in anything bigger than a 5gal tank for the simple reason it leads to more stress later on down the road, and easier for them to get sick, board, become tail bitters etc. My experience might not work for another person its what I developed over the years in keeping fish all kinds and works for me like they say what works for one might not work for another person and for many reasons.
As many know its about theory, but also really need to have experience and practice to make the theory work
I know it seems like I am a jerk after this post but putting in what I think, but like I said what works for you might not work for me and what works for me might not work for you. Trust me when I say this some of these remarks I feel like a hyprocrit thats how its spelled right? Because I filter and heat my breeding tanks, but basically alot breed with no heater no filtration because its to much stuff in the tank!(Breeding tank is actually kinda different in a way)
I think a 2gallon is fine enough, really does the person need a heater depend on temp in the house he might not(but then what do you do for treating it for ick lets say for an example), does the person need filtration erm sticky situation probably not easier to do waterchanges daily! I must say and point this out the drip system that is the smartest thing to come along to the betta world! If this was me and had a 2gallon setup I would use ammo-lock to help with any ammonia and get rid of the filter! Keep it heated I would do!
