yeah, so far i have some feeder shrimps in the 4ft planted community tank, and yamatos too...
Doesn't have any problem, they just eat anything that is left...
The feeder shrimps are more agressive towards food as in, when they see the algea pallet or pallet food drown, they will quickly go and snatch the food, they even try to get those food floaint on the water surface, or snatch from other fish like my poor albino cory...

ON the other hand, yamatos are tame and peaceful...
