Finally got around to messing with this. So far, quite enjoyable. Started with 20 fish and now have over 1,200 and "fish slushi's" in the tank... (67.45 fish, to me, is a fish-shake!)
I did notice in the higher-resolution picture that an inserter was put into the water, but confirmed that no fish can be manipulated by inserters whatsoever, but it sure would have been cool.
THIS mod will work well with the new "O-Sushi..." mod to create sushi lines going around your entire base...and then some.
