You might as well give it a try if they're only cuttings from another plant. I've never tried it myself but you've nothing to lose other than a cutting.

Judging from my own personal experience with these plants, they have no problem growing roots. I'm not sure about using them in aquariums though. They don't call these plants monsters for no reason. When I bought mine as a younger juvenile and repotted it, it had consumed every bit of space in its original pot. I had to go up two whole pot sizes when I repotted it, because it had so many roots when I eventually untangled them. And it has already done the same thing in that pot as well. I had a layer of white marble rocks covering the surface, and when I removed them, I noticed that its roots had grown into every nook and cranny, completely filling up the entire pot.

I just got a potbound dwarf monstera and googled this idea.

I have tried the emergent aquatic plant filtration method for a couple years both indoors and outdoors with platy subtropical fish and pothos, equisitum, papyrus, elephant ear, the tradescantias, spider plant, even yellow nutsedge I pulled from the storm water ditch, big box store orchid, anything I knew rooted easily in water that came my way. As mentioned above, the main problem was light levels. The pothos died in any sun and the equisitum and papyrus needed full sun (or a high pressure sodium bulb beam). Many plants became chlorotic too easily because I was nervous about ammonia levels for the fish so did frequent water dilutions. I am going to try some monstera pieces in my indoor "pond" and am reviving this thread to read about what others are trying.

I cannot think of a better way to learn the basics of aquaculture.

I'm also considering growing this plant in an aquarium. A friend of mine did so and he's not complaining

hmm, now I wanna buy an aquarium

hey, like the idea though! I like the fact that the aquarium which we think of as a home for fish, can be also a home for reptiles ( terrarium in this case) and for flowers. Though I've never met a person who would keep his plant in a tank... But I guess it is possible ? :D I've bought myself a fish tank not long ago and didn't know what deco to put in it, so I came across this site about live rocks and decided to give it a try. All I mean is that if some rocks can look dope in an aquarium then some flower too.
