Mollies at bottom of tank

[HarryB]

Hi,

Just bought 4 new mollies. 2 swimming around fine but other 2 are just at the bottom. Why is this?

Thanks

It's hard to tell without more information, I'm afraid.

How big is your tank and how long has it been set up? Do you know if it's cycled, and what the pH and hardness of your water are? Are there any other fish in the tank and, if so, how many and what species?
