Best material for a tank divider

  • We are currently upgrading MFK. thanks! -neo
I used egg crate and zip tied suction cups to the top for support. Held up strong with over 8000gph in my atf tank. Just jammed the bottom into my substrate
 
Securing egg crate is tough, specially with strong cichlid. Suction cups last about 3 months and harden up.
 
I agree, a large, sexually charged cichlid can easily topple an unsecured divider, so along with vertical pieces, I put heavy stones on both sides of the divider on the horizontal parts, the stones also afford a place for the female to put eggs, if she is so inclined.

That is very cool!!! how did you make that with the egg crate? I just have a piece wedged in with a few suction cups and the midas pushed the whole thing up and out of the water last night!

Interested in how you fabricated the divider?
 
I fasten the eggcrate together with zip ties, cut a notch near the top to wedge tightly in the tank rim, and weigh the horizontal pieces down with heavy stones.

+1 on egg crates

The only damage I've experienced were with 2 flowerhorns that pretty much wanted to kill each other so bad... that they didn't care that their mouths were getting all mess up.

I secure the egg crates with the snap-lock suction hooks from lowes.
 
Egg Crate. Its not that complicated. Anything you can think of to help support it will likely work. My Trimac has scuffed her face up a few time trying to bash through it and reach her target. But no real damage. It's healed in less than a WC.

Egg Crate is best bar far unless you have an elaborate bridge setup with slotted dividers and such.
