It has been a few years since I've had a tank up, but this was my 75g softie reef at its best in 2010.
Link to my tank from 2010, medium green Long Tentacle on left and medium/large red Long Tentacle on the right. I haven't had a tank for about 10 years at this point. The green was my significant anemone success story. I put it in the tank and it crawled into the rocks and disappeared, I thought it had died, 4 months later it came back out front and was about 2 inches in diameter and almost clear brown. With feedings and good light it grew to about 10 inches across in two years and colored up to a nice bright green.
