I've heard 1 peppermint per 10 gallons is a rule people follow, but why is that the rule?
Is that what's most efficient for aiptasia control?
Will adding more cause aggression?
Will more shrimp pose a much more serious risk to corals?
I've heard they can be aggressive if there's too many but...
Peppermint shrimp are a popular invert for their ability to eat invasive aiptasia anemones.
Unfortunately, the best species of peppermint shrimp (Lysmata Wurdemanni) isn't available in Australia due to the only native species of peppermint shrimp being Lysmata Vittata and biosecurity laws...
