I lost my first batch of clownfish after day three. I had heater set at 81 degrees. A small LCD light was shining on a towel which covered half of the tank. The 10 gallon tank was half filled with water from my reef tank. I fed them rotifers which I filtered and then added RG complete to the tank. I could see the rotifers in the tank. I changed 1.5 gallons of water twice a day and vacuumed off the bottom of the tank each time. I then added new water from the reef tank each time. The bottom of the tank was on a white towel and the sides, back and front were covered with a black plastic bag. I had two tiny ceramic air stones barely bubbling a tiny stream of bubbles. One of them was under the heater. I hatched my eggs by moving them to the tank on a piece of slate. I had a great hatch rate. Any suggestions for my next hatch would be greatly appreciated.
