HELP! I just found another one dead!
I dont know whats going on
Ive taken pictures of him


I quickly went to the shops and got some new clean stones and a plastic tank, and covered it with this plastic stuff that they had at the pet store. They're in there now with some water.


I just really don't want to lose any more :'(
Is there anything i can do to prevent this from happening again?
Thank you
