i'm sad.....
two platys i keep have died!!
that day,i put the aquarium in the sun and forgot to take it back,when i came back,i found my two pilgarlics were going to die.....
they suspended in the surface...and can not move agilely...i put the finger into the water ,the temperature was in high..
i soon exchanged the aquarium into fresh water..however,the next day,
