I wish I had a digital camera so I could have taken pics of my emperor while he was growing up. I bought him several years ago, he started changing to his adult coloration after about 8 months in his 75 gallon home. Fed purple sea veggies, ON marine angel formula, and lots of krill, he grew rapidly. he was a good 8-9" long when I transferred him into his new 180 g home before he died. Not sure what happened, I had the tank (180g) running for 4-5 months with approx 80 lbs of live rock and about 10 anthias (which were doing wonderful) in it. Then the day I finally decided the 180 was ready and transferred ââ"šÂ¬Ã…"œthe pimpââ"šÂ¬Ã‚ along with yellow tang, blue hippo tang and pair of gold stripe maroons into the tank. Lots of SPS corals and all the 120 lbs of live rock that was in the 75 also went into the tank. For the first few days everything was going great, then all hell broke lose. Lost all the fish except the clowns, would have lost the corals but I was able to move them into a friends tank in time. After my investigation, I determined that all the sponge on the rock from the 75 died in the transfer and polluted the water. I would kick myself in the *** if I thought it would do some good. That is by far the worst feeling in the world.
