Ugh. I failed to remove them, tried to scoop them up and the two got away from me, to where I couldn't see them, and I'm pretty certain I saw the dreaded gamete cloud.
Now I need berghia (which I'm okay with, more of a shame I wouldn't be able to keep them alive indefinitely), and a way to keep said bergia out of my overflows.
Any suggestions?
For the last, I'm thinking of cutting up an old fish net and somehow clamping it in front of said overflows... though I guess I'd want to eventually put some in the filter section itself to deal with any infestation there?
