That seems like a good way to go.@PaulB is great and inspired me to feed clams (and white worms and baby brine) to my tank. I buy clams in bulk from Costco. I cut them in half w/ a big butcher knife, then freeze the halves - and feed a half clam 2-3 times per week. A $20 bag lasts a few months, fishies go nuts...
Easy and cheap, you're speaking to me!If you don't want to bother with shucking the clams you can purchase clam meat in a small tub in the seafood section super cheap (refrigerated). I buy one every few months and distribute into a few ziploc bags then freeze them down. Nearly all fish will eat them if it's cut up small enough.
