The X12 puffer arrived quickly and looks healthy. I’ve kept it in a 30-gallon tank with stable water parameters. It’s active and eats regularly, though it does show aggression toward other fish. I’ve had to keep it alone to avoid stress.
David Turner –
It’s a small fish but very active. I’ve maintained the recommended water conditions and it’s adapted well. Feeding it small portions of frozen foods keeps it happy and healthy.
Natalie Clark –
The fish is aggressive and not suitable for community tanks. I placed it in a tank with no other fish, which worked. Water parameters stayed stable, and it seems to be adjusting well.
