x2 on the sting. I recall Jimbo ordering one for his 1000g system, we put it in the tank after acclimating it. It started heading for the back of the tank so I thought I would gently coax it to the front of the tank.....mistake.
Also x2 the condition in which they arrive. If I remember right, the first one arrived to John at Aqua Hut in near death condition. Knowing this, he offered Jimbo another for free if the original didn't make it. It didn't so he ordered another. That one did great.............until one of his maids closed the top canopy doors causing his tank to reach 90 degree temps for a day. Lost the malu along with approx. 10-15k in fish and coral.
Moral of the story: don't buy a h. malu.
