ya i feed them alot and water change every other day but as of late im water changing every day. there is blue/green speckling on the tail fin and dorsal and i think in the body too. i need about another .25-.5 inch on these guys and there should be some defining color. cant wait to see. if they keep up the traits im observing now there going to be some amazing fish although some of the things im seeing now may fade away. i hope not. i wish i could get some super close ups like some of these guys on mfk do then you could see what my larger ones look like.
