Fish Crazy
ohhh, and if you leave your light on, try to leave them on for 11-12 hours- when you wake up tell you go to sleep. i leave mine on all day. if you leave them on this long you should lower the tank temp. atleast to 74-75 degrees, the light will riast the tanks temp to about 78 in the day.

is this normal?
and one of the fish is mean as hell, it likes to chase other fishes and now half of the fishes have a split tail. What should I do? this is my only tank and it's not fully cycled
. She also sounds like she's rather ignorant when it comes to fish. If you can't stop her from sticking her nose in your tank, maybe try to educate her, so you don't suffer from her ignorance.
What she did was not funny; it was not the thing any kind of a friend would do.
