They do show alot of red in them. i have seen full grown gold severums and they dont look like mine. mine have alot more red in them. especially the males. must be their diet. i feed mostly hikari bio-gold plus, romane lettuce, and sometimes bloodworm. thanks to all that replyed to my thread. the "scratch" had me worried, as it seems alot of threads have been popping up about tanks busting or cracking!
