This is a great suggestion. +1Another good thing to do with them...they love this...at least mine do.
Since they hang out under the flow of the filter....lift the filter media up and down a few times like you are rinsing it out. This will help "flush" the goodies from the filter box into the tank and right into their fans.
That makes sense. I think that the benefits of the UV sterilizer outweigh the inconvenience of having to feed the shrimps. A possible workaround would be to run the UV sterilizer while you have a problem and supplement feeding the shrimps while you do so, then once the problem is gone simply turn it off.It kills microorganisms. Therefore less will be propogated, leading to a lost source of food
