Hehe....funny little bugger Wrasse; the ol upside down trick; any excuse for a feed.
Sorry Raptor,not sure i agree... it's my understanding that the Blue Tree comes in a variety of shades of blue through to black. It appears to be an odd genetic trait that pop's up every now and again; in populations of common tree's up the east coast.....not sure whether anyone's seen them in the gold phase animals in Territory? Some bluish green animals throw juveniles that maybe green, blue, or black. Some blue phase animals also may throw a mixture from what i've seen (shades of blue green)...however you better the chances of blue babies, from blue adults. Having said that; a well known breeder of them; told me to pick my animals on the colour of their throats as juv's ( from blue adults).....the whiter the throats the chance it's more blue as it ages; the more yellowish, the more chance of a blue green mix.
Regardless, light blue, dark blue, green blue, green, green yellow, yellow, orange, black etc; the colour variety they come in is amazing; i love them all.
