so I've noticed this weird white stringy stuff growing on the decorations I have in my 10gal tank. I just did a water change in which I cleaned the decorations pretty well (no soap, just hot water). Well those little stringy things are there growing again and I have no idea what it is or how to get rid of it. Here are some pictures:
How big is your aquarium? You could get a bristle nose if the tank is at least 30g, or if you have a tank to upgrade it too once it gets larger. You would need to add veggies to the tank(broccoli, cucumber) or the pleco won't be healthy, they also enjoy driftwood. A couple otocinclus are also known to be good cleaners.
And you can always just take the decorations out and scrub them.
