🧳Transporting a Angelfish: bagging, acclimatisation, moving

Angelfish : Transport each adult in a tall, wide bag, as its fins bend and get damaged easily. Slow 45-minute acclimation in temperate water.

In short: 15 cm long and up to 20 cm tall, 240 to 300 L for a group, water between 24 and 28 °C. A majestic, slow cichlid, peaceful in appearance but territorial when breeding and a predator of very small fish. Its tall silhouette demands a tank at least 50 cm high; do not mix it with neons or shrimp, which it eventually eats.

Bringing home or moving a Angelfish

The bagging rule: double thickness, one-third tank water to two-thirds air, kept dark in a cool box that protects from swings away from its 24 to 28°C comfort zone. Split the group of 5+ across several bags: less ammonia per bag, fewer losses if one fails.

Acclimatisation: the critical step

Once home, float the bag for 20 minutes so the water reaches the tank’s 24 to 28°C, then add tank water in small doses over 30 to 45 minutes, and release with a net without pouring bag water into the tank. In this species, a botched transfer is paid for in bouts of hexamita (hole-in-the-head) in loaded water. Keep the light unit off until the next day: a freshly arrived Angelfish settles better in half-light.

Moving an entire aquarium

A house move takes planning: fish in bags or covered buckets, filter media kept damp and warm in a cool box (your bacteria are gold), plants in wet bags, and the tank restarted the same day with as much original water as possible. The tank itself travels EMPTY: glass stressed by a few leftover litres cracks at the first corner.

Frequently asked questions

How long can a Angelfish handle transport?

Properly bagged, a Angelfish lasts several hours unharmed — and up to a day in a professional oxygenated bag. The real battle, past two hours on the road, is holding the temperature.

How do you acclimatise a Angelfish safely?

Float the bag 20 minutes, add tank water gradually over 30 to 60 minutes, release with a net, lights off the first day — and never pour bag water into the tank.
