Yes, with three moss balls in this tank I am not going to risk it. I don't have $20+ to replace them and have had them for over a year now. They pearl like crazy too! It would be akin to me treating for ich while having scaleless fish. They might do okay, but why should I risk their health like that? I have other options.
Here is a picture of the tank in question. I just culled a bit of the anacharis, but it will be back soon enough to fill in the middle space more. I suppose I could raise the sub so that I could put more rooting plants in, but I don't want him to lose too much swimming space. Everything pearls like crazy, so I am not worried about health at the moment. The java moss reproduce every few months, the anacharis grows a few inches a week, and the lucky bamboo, though not pictured, sticks up a good 2.5ft out of the top having grown 2ft in the last year.
