how does the moss ball deals with our temperature?

Here's mine

This thread is sometimes very creepy.... with people talking to plants...

Your container looks kind of small. I doubt the marimo can produce enough oxygen for your guppy so eventually the guppies will suffocate.
So yes, a pump will aerate your water and provide oxygen for your guppies.
However, a pump by itself is not a filter (unless you pair it up with an undergravel filter).
Again, the marimo will process some of the fish waste but not enough.
So unless you are willing to change to a bigger tank, add filter and stuffs like that, I would suggest to do more water changes.
Maybe 2-3 times a week.
Be careful not to kill your guppies with chlorinated water.

While not wrong, I would say that your analysis is not complete.

Those slimy dirt are probably algae.

First thing I would recommend is to reduce the food you are giving your fish. If those things floating on top are fish food, you have given way way way too much food.

Secondly, I see that you have a sponge filter there. It actually needs an airpump to work. Unless you purposely turn it off to take the picture, the lack of bubbles indicates that you need an airpump. Also, it's not clear to me at all, but you might want to add in more filter material into your filter. And clean then regularly with non-chlorinated water (you can do this with your aquarium water when you do water changes)

Now that we are at water changes, just do them. Half a tank a week maybe?

Lastly, I'm not very sure about this advice, but the algae being brown means it doesn't need much light. I read that adding light will reduce it. But you might ended up with green algae instead.

There you go, that's my take on it (as an ex-fishkeeper). These advices are not options that you can choose one and ignore the rest. They are all important and I listed them accordingly. You can alter them to suit your tank's need (not your need).

Good luck.

1) Dead leaves, remove them.

2) For your filter, what do you have inside it? I see a big stone to weigh it down, and some white brownish thing (which I earlier assumed to be some sponge).

3) This is an air pump.


4) I would suggest you leave the additional lighting part off first. Let's tackle the simpler problems first.

5) Yes, more plants will increase the oxygen level. But before you really start to over-complicate things for your tank, ask yourself one question:
What type of tank do you want? A fish tank? A Marimo tank? A planted tank with fish?


And remember, do water changes.

Don't mean to nag, do you have a line into your filter?
