Starvation in over-clean tanks. Jumping. Ich (low susceptibility).
Common mistakes
- •Buying for a sparkling-clean tank — they need algae to graze.

Equipment & food for this species
Needs film algae available. If your tank is sparkling clean, supplement with nori sheets daily.
Nori sheets (Maruichi or Sushi-grade)
