They've been berried for a couple weeks, maybe less, so I have been anxiously watching and waiting. Those bugs came out of nowhere. I've dealt with all kinds of snails and some worms, but never the bugs. That's so cool how stuff just shows up. I haven't had any additions to the tank in months. I boiled some wood and soaked it outside over and over again for a couple weeks, I don't like the tannins. Maybe they came from the driftwood while soaking outside. I'll just siphon the water with the copepods into my tank with fish, they will probably love it. I'm glad they're harmless, but they drive me nuts. Thank you everyone for your comments.
