Marimo Moss Ball

[fishlearn]

Hi,

I got some Marimo Moss ball, that I put in a small container.
They are alone without any fish in it.

Just to check, will they be OK just being in normal tap water?
Or do they need anti-chlorine water?

If you are quarantining the marimo moss ball, tap water is fine. The chlorine in the tap water might be able to remove some unwanted pests before you transfer them to your aquarium.
If you just want to grow the marimo moss ball, tap water with weekly or fortnightly changes with indirect sunlight will do.
But do note that marimo moss ball take really long to grow, about 5mm per year.
