The leaf fish arrived healthy and active. They immediately started hiding among the plants in the tank, which is exactly what I expected. Their camouflage is impressive and they seem to be adjusting well to the environment.

I’ve kept several species before, but the leaf fish stand out for how well they blend in. They don’t move much, which makes them look like real leaves. I noticed they’re active at night when hunting for small prey.

Great addition to my freshwater tank. The fish are calm and stay hidden most of the time. I appreciate how they don’t disturb the other fish. They look natural and add a realistic touch to the ecosystem.

They were fine at first, but after a week, one of them seemed less active. I’m not sure if it’s due to water conditions or just individual variation. Still, they look realistic and are a nice visual element.
