Bug in fish feeder

All critter feeders overserve this behavior, if multiple species can use it as food it will all be selected after re selecting the critter feeder or fish feeder. 

What do you mean with "The second issue is that, the pool is always empty, so that my fish is starving", i do not see any bug in your YouTube link.

I do see the bug and I'm having the same one. The duplicants loaded the feeder but the pacu never eat the loaded food. They never get tamed or if a tamed pacu is placed they starve to death. Some times the seeds or algae are not shown in the the feeder as the usual green dot, and even if they are shown the pacu still don't eat the food as you can see in the attached images; I'm also noticing that the feeder is somehow dissociated from the material whenever I build one I can also see a a metal ore separated indicator, this happens when I build the feeder with gold, copper or with any other metal. This shouldn't happen, please help!!!
