Hello new to aquarium fish hobby

[Germangood]

Hello I have a 100 litter aquarium with some molly and 2 L fish with some colored fish

Right now im happy with the aquarium setting
Gonna add 3 white molly to the aquarium
And thinking to add more 3 ballon molly
Is there any suggestions of fish that will go in that tank?

Is it ok if I bring one beta fish to the tank?

Forget the beta. They are not exactly good community fish.

Forget the balloon molly as well, they are very deformed fish which have health issues because their internal organs are squashed.



Do you have hard water or soft water? We need to know before we can suggest fish. it is better to keep fish which come from water with similar hardness to your tap water.
Mollies are hard water fish. The photos show glo-skirt tetras which are soft water fish. One or other won't be healthy long term, depending on the hardness.

Welcome to the forum...
Yes, some more info could help us to make suggestions on new fish. But also realize that your current mollies will reproduce in there as well... Which makes the number of fish higher at some point.

Oh so the balloon one are not that healthy got it

About the water I poured a glass of water and its clear and some people drink it so i think i got soft water, no gray matter.
I like the Mollies is there any fish going well with them?

Greyness and drinking have nothing to with hardness.
Hardness is a measure of the amount of calcium in the water, some places have soft water, some have hard water and others have hardness in between. It is all safe to drink.


Fish have evolved in water of a certain hardness.
If fish (such as mollies) which evolved in hard water are put into soft water, they suffer calcium deficiency and become sick and die more easily.
If fish (such as tetras) which evolved in soft water are put into hard water, their bodies store calcium and they often die from calcium blockages in their kidneys. They don't live as long as they should because of this.

The only way to know your hardness is by testing it. Your water provider should test for hardness and many providers give your hardness on their websites. The first thing to do is look on your water provider's website to see if they give it. You need a number and the unit of measurement as there are several different units for hardness. If they don't give it, you can buy GH (hardness) testers to test it at home.

I have a water tester a tested the water and it says i have 364 PPM is it helpful?

 

[Essjay]

Yes, that is very hard water. Mollies will be fine, as will most of the common livebearers and rainbowfish.
However it is not good for soft water fish, they won't live as long as they should in that hardness.

When choosing fish to go in the tank, you need to check first whether they are suitable for your hardness. The profiles in Seriously Fish give hardness ranges so check there before buying.

Some profiles give the hardness range in ppm, others in dH. Your 364 ppm is the same as 20 dH.
