The tank looks great!! and as for the fish they look to be doing great as well. I am sure that they will get used to the other foods. I find that if I feed bloodworms too often my fish will start to get picky and not eat the Tetra Bits so I have to back off on the worms and feed the pellets in the morning when they are the very hungry. Of course they always go for Al`s BH mix.
Keep you momentum going your doing good.
