The tradeoffs, honestly

Lionfish stings are painful and need care, and they will eat any fish or shrimp that fits in their mouth. Some need patience to wean onto frozen food.

Common questions

How dangerous is a lionfish sting?

Very painful but rarely life-threatening for healthy adults. Soaking the area in hot water helps, and medical care is wise for serious stings.

Will a lionfish eat my other fish?

Yes, if they fit in its mouth. Keep them with large, robust fish only.

What should I check before buying, and should I quarantine?

Ask whether it is eating frozen food, and look for a full belly and clear fins. Quarantine new marine fish to screen for ich, velvet and Brooklynella.
