Filter for an apisto couple

[Matías]

Hi everyone, a couple of questions:
Do you know which would be the best type of filter for an apisto (Apistogramma baenschi and Apistogramma cacatuoides) couple or trio?
Would you recommend the use of sponge filter in a 20 gal (75 L) aquarium (that contains plants and sand)?
Thanks!

Sponge filters will be great for them. They won't suck up sand or fry.

Hi all,
If you already have a canister filter or HOB, you can make it fry safe by placing a sponge over the intake. I DIY most of mine from PPI10 or PPI20 foam sheet, but you can buy suitable ones ready made. I have them on all my tanks, they stop debris (as well as fry) ending up in the filter, they are easy to clean, and they provide a browsing surface for shrimps and fry.

These are some small ones, but I also use much larger 12" x 4" x 4" blocks designed for Koi carp ponds.

and in use (right of the picture).

cheers Darrel
