cire9 - LMB & yellow perch bad mix. Put this in the for m of a question in the forum heading Types OF Fish TO Choose and I will address this topic.
I'm pretty sure it has been talked a couple times previously in other posts. A search in Quest & Obser. and other fish topic headings may reveal the info. I don't want to talk about it here and bury it under the topic of aeration - systems questions.
