Free Floating Frog Spawn Larva?

[calvinsmarshall]

Hello, I've noticed around 10 or so small, blue/green, free-floating frogspawn polyps (larva?) on my sand bed. Any suggestions on how I might preserve these polyps so they can mature? Concerned that if I leave them where they are, they may get sucked up the next time I siphon the sand. I would attach a photo, but the polyps are so small, they don't show up very well on camera. Thanks much.

You can either set up a small 2 1/2 gallon tank using material from the show tank filter and put sponge around the intake of a small pump or use a bubble filter . Or you can glue netting around shroom cage and clip it or use a magnet to keep it from swimming around the main show tank
