First a bit of background about myself, I’m quite experienced with owning freshwater fish.
I currently own tanks with guppies, red-tail sharks, mollies, gouramis, mbunas, catfishes, platies, shrimps, clown/kuhli/yoyo loches, etc. And i think i’m doing really well with it.
However, i have never owned a Betta, or a Goldfish, though i have an idea of how to treat them.
But I have never owned a mini bowl tank. Unfortunatley, i have received a “betta bowl” for xMas, that looks similar to this in terms of size:

Given that I will make use of it, probably putting my first Betta in…
~~~First (set of) question:~~~
How does it really work?
As in, would you even cycle that?
Would you bother putting gravel in it, i’m planning to have horn wort in it, which doesn’t necessary need gravel.
How do you do water change? I don’t think vacuum cleaner is an option. It’s so small too, wouln’d pouring water in and out so stress the fish?
And given how small the bowl is, how often do you change the water?
My room is quite cold in winter, maybe 10-15 celcius? You can’t put a heater in that thing.
Right.. i really dont’ get how those stores can have maintain those cups of bettas…
~~~ Second (set of ) questions: ~~~
Please don’t kill me, but on the box, it says don’t get mistaken by the name, thought it’s called “Betta Bowl”, you can put a golfish in.
Now i’m pretty surprised, i thought Goldfish needs BIG tank for how messy they are. So I think it’s lying.
But in case i’m wrong, do you know any kind of GOldfish that can be happy in that bowl?
THanks!
