Two important purchase criteria were that the filter shrimp is safe as well as small.
When cleaning is depending on how you it händelt part of the filth from the filter back to the Aqua, naja.Aber about Mul most pleased the little shrimp and also get so no baby shrimp into the drain :).
I suppose that cleans out all the filter and rinse the filter again by, but in a bucket. If times small shrimp in the filter are that they do not inadvertently fall victim to the drain.
I have to say this, so far it has only one shrimp in the shrimp filter geschafft.Diese scurried after the Liberation action again alive and kicking in the aquarium rum.
