Just bought as a small gift - how long can they keep out of water? Are they salt or fresh water or both?

Apparently they can survive up to a month out of water, although I haven't tried it, and can live in fresh or salt water. Mine are thriving just in tap water which I change every 2 weeks.

Why are mine floating at the top of the tank? How do i get it to sink to the bottom?

I have found that when I clean them by squeezing them gentle and then put them back into clean water they float for a while but eventually they soak up the water and sink to the bottom. I keep them in water that is about 9cm deep.

Can I just put these straight into my tank or is it best to wash them first

You can put them straight into your tank They will probably have air trapped in them so you will have to hold them in the water and gently squeeze them and if they arrive as mine did whilst gently squeezing them you will have to shape them back into balls

Hello, can you tell me, are these good to keep with betta fish

As far as we are aware moss balls are fine, they help keep the tank clean
