Some internal filters as shown by @wasmewasntit above come with venturi where they suck air from the outside of the tank, and push the air into the water.
This works the same as an air stone though it pushes the gas from the middle level of the tank or depending on where you place the internal...
I saw some of these totes/tanks that are made by fiberglass.
They are stronger than the normal plastic though I have never used them before.
They are good as fish ponds for fish like Guppies, Koi, Goldfish, etc..
If I'm not wrong, some of these fiber glass tanks are now being used even in the...
I forgot to mention this.
Usually my arms won't go inside the tank unless I want to wipe the glass.
But with the water at low level, my arms won't be touching the water.
Only my hands that will go inside the water if I need to wipe the bottom of the tank(for tank with bare bottom).
If it still can swim after 2 months, then most likely doesn't carry any disease that can infect other fish(IMO).
Probably it's only a swim bladder problem of some physical defects/abnormalities.
But if it doesn't eat for too long, it will also die...
Don't worry.
I don't think it can spread so easily through tap water.
According to the doctor in the video(from his posted comment), he had only encountered 3 cases during his many years of seeing patients.
It spread mostly through an infected fish.
Just make sure your hands don't have any...
I don't think it can survive long at this condition.
A fish that is lying down at the bottom of the tank is usually at terminal/last stage of its life.
Is the fish breathing very fast?
The fish is sick and can infect other fish if it's having disease(parasites or bacteria).
It's best to...
You can get one of this siphon.
Most siphon should be able to reach the bottom of the tank unless your tank is very tall(more than 2 ft) or you have a very wide(front to back) tank.
You can also modify it by getting a longer plastic hose (the part which I circled) if
your tank is too tall and wide.
I don't have experience with Betta Pugnax.
But my experience with Betta Imbellis (another wild Betta), they are very peaceful.
I kept them with Cardinal Tetras and Green Kubotai Rasboras in a 25gallons tank and my Bettas didn't bother the schooling fish.
I think you can consider the average...
By the way, usually you don't put your hands inside the tank as it will pollute the water.
If your hands have soap or detergent, it may kill the fish.
The only time when I put my hands inside the tank is during the cleaning/maintenance time.
But during cleaning time, I will siphon out most of...
Are you going to have half land and half water in your tank?
GEX has some filters that can be used for this kind of tank.
It's called GEX turtle filter or corner filter I think.
Get the size that can suit your tank volume.
If you are unsure about the filter size, get one that has flow rate of...
Most fish like Bettas or Cichlids will protect their territories especially during breeding time.
You can search the internets for stories of fish biting and attacking human.
By the way, you can also consider an internal filter.
Get one that suits your tank size. Most filters are rated for the tank size.
If not, get one with a flow rate of 3-4 times the volume of your tank if you are keeping Betta.
For most/majority of fish, I usually get a filter with flow rate of...
Actually I like all aquatic creatures...
The more the merrier...
Fish, unique fish, shrimps, crabs, crayfish, mudskipper, etc.
Then you can create a natural habitat with a complete ecosystem in your tank...
.
I agree with @Byron.
The tank space will not be enough for 2 groups of fish.
Get one group of Boraras Brigittae(Chili Rasboras).
You can probably add some Cherry shrimps.
For plants, usually I like fast growing plants such as Anacharis Elodea or Hornworts.
You can keep them floating on top to...
If I can get access to a river, probably I will bring a big fishing net.
Throw it into the river and pull it up.
You can catch many aquatic animals from shrimps to different kinds of fish.
But take care of your safety if you are not familiar with the river and place.
CRS (Caridina shrimps) must have cooler water compare to the Cherry shrimps(Neocaridina shrimps) that are more hardy and able to take warmer water.
What is your water temperature?
If you can maintain this cooler temperature especially during your summer time, then you will be fine.
They...
I think it can be difficult to buy separate hood.
I think the best is to buy a tank that come with the hood in my opinion.
For Betta, 10gallons is more than enough.
If you get a 20gallons, don't get Betta.
Get other more peaceful fish that can be mixed with other schooling fish.
Adult Kribensis can be aggressive.
In the past, I had one that chased all other fish even my Blue rams were picked on.
In the end, I had to remove it and place it in another tank.
Get another tank as soon as possible.
If you are short of space, can you get a two tiers aquarium tank as attached below?
Put one tank on the bottom and one on the top tier.
But check the stand exact dimensions as you may need to use a wood to support the bottom (if you buy the metal stand
without the wood support)
I agree with all the above. All are nice.
But for myself, I'll get bored over a single species after a while, so I will choose Option 3.
I'll get fish that are less nippy and more peaceful.
I'll create a community tank with a group of top/middle level fish and some bottom level fish (dwarf...
Sorry, I re-edit my post after realizing that you're living in a temperate country where the air inside your house can be cold during winter.
But if you have heaters to heat up the air inside your house, probably it should be fine for ideas 1), 2) and 3).
But if your house doesn't have heaters...
I agree with @OliveFish05.
Increase a few more Neon Tetras and return the Rummynose Tetras.
They won't school together because they are totally different species.
Neon probably can school with Cardinal Tetras but not Rummynose Tetras.
Rummynose will also need bigger tank than Neon Tetras.
By...
I think it depends what do you want to see from the fish.
1)In terms of colours, Cardinal and Neon Tetras have the most striking colours.
2)If you want the best tight schooling fish, Rummynose Tetras is the best.
3)If you want more hardy fish with nice fins, Red Phantom with yellow fins, Rosy...
I agree with @OliveFish05 .
There are many factors that determine how long a person is keeping fish.
For me, there are a few main factors:
1)Availability of time
Some people due to their busy schedule are unable to keep fish especially when they have just started a family.
The fish that require...
Get a good hose like JBL hose for your tap but ensure that the size/diameter is correct.
It will speed up your work and make it easier to do water changes.
Get a power extension cable for your water pump so that it will easier for you to control the on and off switch.
Actually, I don't use any...
I don't see any white spots.
If it's white spot(ich), you need to continue treating for another week after all the white spots are gone.
You need to treat the eggs of the parasites which are not visible to our eyes.
If you use heat, you don't really need to use medication.
But for heat...
I bought a pair of Cacatuoides last year but it turned out to be both male.
It's a problem when the fish farm is dishonest selling young male that looked like female..
But both are coloring up nicely now with beautiful spiky fins.
Beautiful fish and they don't grow too large which is good for medium size tank.
Probably I should get this in future. LOL

In my opinion, they are ok with just 1degC higher.
It will be difficult to find fish with the exact temperature as Blue Rams.
You may have to abandon the idea of Blue Rams.
Or just keep a group of Rams with Cardinal Tetras, Green Neon Tetras, etc.
There are 3 colours of Rams - Blue Rams/German...
The Bleeding Heart Tetras are quite fast swimmers.
But take note that they look quite like Rosy Tetras, Red Phantom Tetras or Serpae Tetras.
Bleeding Heart Tetras have a red dot on their body which distinguished them from the rest.
Red Phantom Tetras are slightly smaller than Bleeding Heart Tetras.
