well its a good deal cause theres more females then males in the hets group . plus the albino all together ya its easily worth $600.00

and to me that cage looks like is the hatching cage ,
theres perilite underneath the papertowel so that tells me its set up to stay moist for the balls until their first shed . yes i would clean it more often , but the discoloartion isnt always from urine , could be residue from the eggs coming off the balls ..

not justifying their tank condition but shouldnt just jump to "filthy cage " determination without knowing ...
