"This species is anything but timid, it is very capable of holding its own. But more importantly it is not just a micropredator, it has a taste for shrimp. It will quite happily take on mature shrimp twice its size, especially cherry shrimp, which will either eventually be eaten or chased out of the tank (if it is open top). It also hunts in packs, which increases its effectiveness no end. It is in actual fact a born shrimp killer."
"I’ve kept a pair in a 25l tank with a few adult cherries without issue. However, when I had Caridinia simoni simoni in with them, they would predate the eggs while the females were still carrying them, and I never had a single shrimplet survive."
