I'm going to be fishing for baby longear sunnies pretty soon, probably in a week or so when things warm up. I found a spot with a bunch of them, but there are some adult blacktail shiners there as well. On the off chance that I catch some shiners, would it be a bad idea to put a couple in my 65g with the younger shiners I caught yesterday? The little ones are about 1 2/3" long, the adults are more like 3" and up. Will the size difference cause any issues?
Also, can adult shiners adapt to captivity fairly well, or should I just put them back if I get any?
