Yup food bill is getting higher, I spend about a $120 on earthworms alone a month. I just got my bigger rays on raw shrimp so that should help out a lot.
yea shrimp is a lot cheaper than that... IMO get them on pellets and that is even cheaper.. IT seems high to buy pellets but they last a good while. My bigger rays are on almost a 100% pellet diet and are breeding like crazy.
