- Behavior
- Pacific
- Compatible with fish
- Peaceful fish that won’t chase it; not suitable for demanding Caridina shrimp (different water parameters)
- Diet
- Primarily algivorous (filamentous algae, GSA, BBA) and detritivorous
- Reproduction
- Oviparous; larvae require saltwater—they do not reproduce in freshwater aquariums
Notes: The best algae eater in freshwater aquariums. It eats thread algae, green spot algae, and BBA very efficiently. They do not reproduce in freshwater (you must purchase adults). Larger and more active than Neocaridina. Highly valued in aquascapes for algae control.
