There is but it will require your patience. It will take a long time to persuade the loaches to show up. They generally don't show up a lot where plenty of big fish are present. Explain to your parents why you cannot keep the blood parrots there. The tank itself is overcrowding with the peacock basses around. Is there a reason why you have 4 peacocks? If at all possible, persuade them to buy you another tank for the parrots if they refuse to move those over.
The only fish I find suitable with loaches in your tank is the flagtail.
P.S. To be honest, I don't believe in those so-called lucky charms. It's all a marketing ploy if you ask me to persuade some people to buy these fish for a quick buck.
