Besides brineshrimp
 

Is it possible to feed either microworms or vinegar worms as a first food for new angelfish "wigglers" that are just starting to swim? I'm trying the brineshrimp, but having a heck of a time getting enough. About to buy better eggs and seives to see if I can improve that operation, but that may be late.

I dont see why not. I have seen micro worms used on bettas and I use them for my catfish. I didnt realize that the micro worms needed light. I had my colony in a dark location and it nearly collapsed.
