I have heard of sunburst;s out of colorado. Seems to be a cross between a flame tip and a speckled RBTA. Very nice, big nipples. Rainbows are three colors/shades. Tend to be more of a camelelion color with diff light. With T-5 (14K) mine was orange to red to green tint mouth with yellow on the tips. Since changing over to LED (18K), All yellow tenacles with orange base with slight green tint.
