I had asked earlier this year on this form whether or not anybody thought a geranium would be able to work in an aquarium so I decided to test it out and I've had great success my geranium in my tank has started flowering I think I'm going to continue and spread it or get different colors only issue cuz every once in awhile about once a week I wake up to find it sitting all the way into the water assuming my Oscar pleco or manganese have knocked it in very happy with how it turned out
