Freshwater Clams

Not a good idea, IMO. I've tried them, and studied the native ones quite a bit. They require tough water conditions--no ammonia/nitrites, very low nitrates. But, since they are filter feeders, they need lots of suspended food particles in the water column. Tough for us to maintain in a tank. They do best in a mud substrate, but most can get by with sand--gravel won't work for them in the long term. Since native species are likely cool/cold water, they don't thrive in our tropical tanks. And, since they do bury themselves and are most visible at night, it's tough to notice when one dies--and they will create quite a spike when this happens.

Another potential problem--if they reproduce, the larvae are fish parasites. Some are species specific so probably not a threat, but still a pain.

JMO, but leave in the streams and lakes.

Another issue to consider is local game laws as well, I am not familiar with OKlahoma, but most states have pretty strict laws on harvesting and transportation, some species are currently protected here in Ohio, and even if you have good intentions, the fines are stiff. Get a set of fishing laws (if you don't already have them) and check it out.

Here's the link for fish and game in Oklahoma.

Native collecting here is basicly it can't be endangered and you have to have a fishing license.
