After months of careful setup, the Lactoria cornuta has settled well in my 120-gallon tank. It’s peaceful and doesn’t attack other fish. I keep a close eye on it due to its reef caution status. A challenging but rewarding addition to an expert reef setup.
Simon Arnold –
This fish is a bit shy at first, but once acclimated, it becomes a calm presence. I’ve noticed it doesn’t eat much, so I feed it once daily. The tank size is essential—100 gallons minimum is non-negotiable.
Penelope Ferguson –
It’s not for beginners. I had to research extensively before adding it. The fish is active but not aggressive. I’ve seen it interact with corals cautiously, so I keep a watchful eye.
