We've been shopping our local Asian market for fish food lately. I've been getting tiny clams for around $3.99 for a package that lasts over a month, other types of sea food for dirt cheap, and last night, 16 oz of little tiny crabs for $3.00 or so! There are easily 40 or 50 in package.They have the top shell removed, but the other shells are intact, so there is enough visible meat to get my puffers interested, then they have to break the shells to get to the rest and fill up. It is now cheaper to feed my puffers than any of my other fish! I'm excited. Does anyone else shop that way for puffer food?
