Peter Piper –
I’ve kept this tiny Threadfin Snapper for six months in a 150-gallon tank. It’s peaceful and active, and it doesn’t bother other fish. The size stays under 2 inches, which is perfect for my setup. Only suitable for expert aquarists, but worth the effort.
Warren Bell –
The fish is very calm and doesn’t cause any aggression. I noticed it grows slowly, staying under 2 inches. It’s a good addition to a large tank with other fish, though it’s not for beginners.
Simon Reid –
After two years, the snapper remains healthy and active. I appreciate that it doesn’t damage corals or compete with other species. It’s a quiet, reliable presence in the tank.
