Oh I forgot, someone wanted proof or something. I think my star polyps spreading 8 inches in under 4 months, my derasa growing 2 inches in under 6 weeks, my kenya tree splitting twice and growing about 4 inches higher, my dusters going from 4 to 6 inches in 4 weeks, (xenias already spread quick) my xenia is currently sprouting its 11th limbs in three months (I have had to frag it 8 times). My trochus snails breeding, successfully. A birds nest that I bought a frag that was, well one limb at about 1/4 of an inch is now about 1.5 inches tall with 5 different limbs......I think that is pretty good.
