Fantastic offering...fanned and watching!! Does this root or is it free standing such as a moss ball? Eh, I can look it up LOL...have not seen this in any of my local fish stores. I have a 90, 55, and 29 gallon....every moss ball I put in gets destroyed. Not sure the culprits...Think its either the Oscars? Sharks? Plecostomus? Brats, all of them LOL!!! Perhaps better for the small frys, this!?!
