so when they are stress they wont eat right? how long will it get use to his new tank? now he just likes to sit on the bottom low corner. and should i change the water? it's a bit cloudy.
You should ask for a test kit for your birthday.
Cloudy water is not a good thing. I would not change the water. Cloudy water is a sign that something is wrong.
I'm guessing you recently set up the tank and added all the tilapia fry? That caused an ammonia spike because there is no biological filter established.
What do you know about the nitrogen cycle?
