The Yellowspotted Scorpionfish is a fascinating addition to my reef tank. It blends well with the rockwork and shows interesting behavior during the day. I’ve had it for six months and it’s still active and healthy. Only recommend for experienced aquarists with stable conditions.

Beautiful fish with unique markings. It’s not easy to keep, but once the tank is set up properly, it adapts well. I noticed it hides during the night and emerges in the morning. The water parameters need to be very stable.

It arrived healthy and looks good in the tank. I’m still adjusting the lighting and flow. It hasn’t been very active yet, so I’m waiting to see how it settles in. Not the easiest fish to maintain.
