No I can't kill them one at a time there are thousands. and for a referecne they are about the size of 1-2 point text. Thats 1/72- 1/36 of an inch. Tiny little buggers
As of yet I haven't done anything.
They aren't hurting my plants at the moment they are just an eyesore.
Actually latley I have been through a disaster in my tank.
I fixed a spot where i thought my anoles could sneak out and inadvertently created another larger one. Long story short they got out. I caught them all and put them back. Except for the one that commited suicide by climbing into my fixture.
Also I added 4 cories. I only have one left now as my tank went through a cycle after I added them and switched to hard water for my snails. It also wiped out my 8 glofish.
I have since replaced them with 3 guppies, a handfull of ghost shrimp (which oddly surived the disaster, and i thought shrimp were sensitive), and on danio.
I am now feeling sorry for my fish as my danio needs some friends and my cory needs some friends.
I am scrambaling to free up my 5g for the guppies, and then get together a school of cories and a school of danios.
I will be trying the dry ice thing once everything is settled back in.
