Hi Guys,

I have a 3 foot x 18 x 18 tank which I an going to put discus into. After they grow a bit, I want to transfer them to my display 5 footer.

I was thinking of getting about 8-10 small ones. Is this too many? I will do 30% water changes three times a week. I also have an external cannister filter doing 1200Lph on it.

Also, I am not going to have anything in this tank. No gravel, wood or plants. Nothing except the heater. Is this OK? Do they NEED somewhere to hide?

Thanks everyone!
