Hello.
I'm still beginner to aquarium hobby.
I need an advice on what's best in this 10 gal tank. I planned to use this to grow some fern, moss, and frogbits, and as a back up tank in case of emergency. After couple months I noticed there are a lot of hydra and tiny oval clear/gray swimming organisms. Hydras are everywhere, even on sponge filter.
Is it better to clear out plants and wash the aquarium? Or leave it as it? Is there any fish that eats hydra and other water organism?
