Update….
The Scuds arrived today. Must have been a couple thousand of them. They came in a breather bag which I’d heard of but never seen. No need to add O2 to the bag. Pretty cool!
I put probably 200 in the 20 G tank and another 40 or 50 in the 5.5 G tank. The rest I put in the pond where they disappeared immediately into the rip rap.
Here’s a pic of my 20 G scud tank.
Here’s a pic of my 5.5 G scud tank
And here’s a pic of a few of the scuds getting busy chowing down on leaves.
