Fish Yawning

[sean rand]

Hi, fish are yawning occasionally mainly my anthias, what can that mean ?

It could be a sign of aggression, it could be they’re just stretching, it could mean gill parasites like flukes, ich, velvet.

All my fish go through 2 -3 weeks of copper and then transferred to a sterile tank for another 2 weeks to make sure they r good

+1 stretching & possibly aggression. If it’s happening all the time then I’d consider the parasites listed above.

Here’s a link to a thread from a year ago that had additional discussion about fish yawns.

If there are no other signs of illness I wouldn't worry. Most of my fish yawn, and it's been years.

Are they treated with praziquantel? If not, flukes are a real possibility since copper does not eradicate them.

A 5-minute freshwater dip will confirm whether or not flukes are present. And luckily, Prazipro is relatively Reef-safe. With the caveats that feather dusters and ornamental worms won’t tolerate treatment, and if you have a large bristleworm population the die-off can be problematic.

Having a water change at the ready, and making sure the tank is heavily aerated... will help to mitigate that risk.

I can dose DT woth prazi, would my starfish survive with prazi?

its part of their common behavior (if you rule out any disease as above) and makes an excellent chance for amazing pictures if you are fast enought to catch them.
