So my algae is slowly going away. I think it's simply from the tank maturing and aging. Now my problem is a huge infestation of seed shrimp. There are thousands of these all over my tank. During the day they're swimming in the substrate and around my Dwarf Hairgrass and at night they're all over the glass. Why did these guys suddenly appear and what's the best way to get rid of them? If I can't get rid of them will they do any harm to fish or other shrimp? I'm thinking of putting Red Cherries in there. Will that be a problem?
