It is best not to feed the loach.

There are two reasons.

1 The loach is too big for scorpions to eat. It's a waste to keep it. Even if we can keep it and take it out, it's already dead. Scorpions may not continue to eat.

The main food of scorpions in nature is insects, small reptiles and so on. Scorpions are afraid of water and fish, and such things are definitely not on its menu. Give them less food that is not on its menu.
