Is it illegal to put a zebra mussel in an aquarium even when they are all around you? They seem hardy and stay small so would not negatively affect the water when they die.
My "friend" has had them in his tanks for 7 months.
Since they don't borrow it's relatively easy to tell when they die.
Two are adults growing slowly with several babies. They haven't taken over the tank by any means, I believe the gold fish and cichlids enjoy eating the baby clams.
I will tell him. ThanksWell your "friend" will have $500 fine if he is caught by posses zebra mussels as Iowa laws says you cannot posses zebra mussels.
