I have a 75g full of MTS, I don't want to kill them, so they are for sale at 5 cents each and a mix of sizes. You will get a lot of free extra MTS if you ask for them. Shipping is $6, it's hot here, no cold packs. Ship Monday and Tuesday, can ship other days at your discretion. Priority 3-5 days, they will be brought into the post office the morning of shipping. Can't say how many I have...but by the looks of it, 200 or more easily. Couldn't get all in one shot, so it's 2 pics put together.
