ok, hummm another thing u could try is market shrimp i feed it to both my 14 inch fire eel, TT eel and rays. They about 20 - 25 bucks in market shrimp a week which isn't bad. Also when we bought the rays we picked up a bar fridge and turned it into a "worm" fridge so we can buy flats of worms at the bait shops. The cost of those worms are about 45 for 500 dewies and they stored in a 5 g bucket in the fridge so they last longer just gotta remember to feed them. We also have a red worm colony started its a composter dose not stink at all and is stored in storage but it takes a wile to get up and running. Also pls be aware ur wife will be happy to know she doesn't need to squeeze poop out of the worms, just rinse off and there g2g, been doing it that way for over 5 years.
