04 — Care Guide
Keep them thriving, not just surviving.
Every order ships with a personalised care card. Our marine biologists are one message away — because a healthy tank starts with knowledge.
Read full handbook →Cycle the tank
Let beneficial bacteria establish for 2–4 weeks before adding fish.
Stable temperature
Most tropicals thrive between 24–27°C with consistent heating.
Live plants
Anubias and java fern oxygenate water and reduce stress for fish.
Feed with care
Small portions twice daily — overfeeding is the #1 killer of fish.
