Fishless counter to nematodes, seed shrimp, copepods? Bladderwort?
My 5 gallon tank has nematodes, seed shrimp, and copepods, and I'd like to know if they'll get out of hand, with me just having cherry shrimp and otos.
I don't really have the room in my tank for more fish--would bladderwort keep them in check? Something like Utricularia graminifolia? I've been reading up on the plant, and though it's not for certain, it seems in most cases their traps are too small to suck in shrimp fry, though I hear UG doesn't like heat. I also know to avoid U. gibba, U. inflata, and U. olivacea, since they're pretty invasive.
