So today i went ahead and bought some azolla. I put it in the tank and realized that the roots were too long for my 5 gal and were creating too much shade + no swimming room for my betta. I tried to research, but didn't find much info on it as far as keeping it inside. i thought a bit and went ahead and cut the roots. They're now about 1 inch and look really nice.
Did that damage the plant? To my liking i would just keep trimming back the roots as they grow to around an inch. Is that ok?
I do have a back-up batch just in case. I actually got too much of it so i might house some outside in the backyard in a tub or smth :)
