thinking

Hi everyone. Ever since I got a fish tank I've always wanted a black ghost knife. Has anyone ever kept one or does anyone know about them? I want to know as much as I can before I buy one.

I have a few tanks, few different cichlids. Im thinking it may be time to start using plants soon. My tanks have PH between 7.6-7.8. I use african cichlid mix in the tanks with 7.8, and regular sand in the tanks with 7.6. I keep the temp in all of them 80f. I have 2 german blue rams, jack...

Okay, I am bored with my fish. Bored with my hobby. I am thinking about taking one of my 30 gallon tanks in the fish room and plant it. What type of gravel or substrate would you use. This will not be high tech but may be gravel and lights.

I am thinking of trying sand for a substrate, for the first time. How thick should I have the bed and how do you clean it?
