Yes!!! It's completely covered the substrate as well. I'll probably hold off on feeding for a while. They'll be okay. Hopefully a good amount will die off

All my fish eat live baby brine but that's not all I feed them. I have a 125 gallon with silvertip tetras (species only tank) 8 tanks total

I just recently started hatching baby brine. Now that you say that it did start around that time

I've been looking up what it could be for over a week now and haven't been able to find anything that looks like it. I just googled Hydra since that's what you said and that's exactly what it looks like. So I'm going to do some searching now to figure out what that is and what to do. Thank you so much

65 gallon high. I've had it up and running for a few years now. I have a fluval light but honestly can't remember which one, I leave it on for 10 hours. I've never had this problem before. Only parameters I was able to take are the aquarium Co op strips. Not sure how to even test for kh and other things like that. I have very hard water, nitrates at 50, 0 nitrites, 0 ammonia. I have 32 Cardinal tetras and 15 harlequin rasboras and 8 corydoras. 10 hours for about 2 months. Before that it was 6 hours but upped the hours when I added new plants and more plants

What's is this? Algae? It's killing my plants and growing at a rapid speed
