That is true.I wouldn't get either, if it were me. Sparkling gouramis love to eat shrimp. Mine would even have a go at the amano shrimp that were three times as big as them. It was no more than a minor annoyance to the amanos, but my guess is that if a shrimp is small enough for the SGs to tear to pieces and eat, they will.
I was hoping to acheive a balance of prey and predator.
