Common Mistakes with Crystal Red Shrimp

✗

Keeping fewer than 6 together

Crystal Red Shrimp is a schooling species — they need a group of at least 6 to feel secure. Lone or paired individuals become stressed, hide constantly, and may develop health issues or aggression.

✗

Putting them in a tank under 5 gallons

While 5 gallons is the minimum, nano tanks require more frequent water changes and leave less room for error. A slightly larger tank (8 gal) is much more forgiving.
