@Luke da Zoo nerd this is not a Ruby Seadragon, that's a Weedy Seadragon that is either particularly vibrantly-coloured or photoshopped. The Ruby Seadragon has only tiny fronds and is a much more vibrant red than this specimen, plus the Ruby has only been seen alive once, and never kept in captivity, so this fish is 100% Weedy Seadragon.
