best free food for shrimp ?

Hi @Wookii, I've never seen these before. A brilliant alternative if a sponge is an undesirable solution!

Cheers,

I'm a big maintenance-phobe, so digging around at the bottom of the tank to pull a sponge off the bottom of the filter inlet every week is a big no-no for me - I prefer to have the pre-filter (and I'd never be without a pre-filter) in the filter.

thanks guy, by the way, does this intake is small enough to avoid shrimplet to go in the filter ? baby snails can't pass it though

I have the same inlet but in white and this is how I've covered the holes on mine with some left over filter sponge from when I customised the HOB filter media. I have plenty of shrimplets now and the larger shrimp pick the inlet sponge clean when it gathers noticeable detritus.
