I have 2 of them. One of them is a single branch and the other has 2 branches.
$10 for the single - $20 for the double. All frags / branches are at least 3" long.
These are non-photosynthetic and will require feeding. They also will require moderate / high to high flow. Lighting requirements are a non issue, they can be placed anywhere where there is good flow. The colony has been in my system since the beginning of June and is doing well. As of right now, they are not mounted but I can mount them to a frag plug.
These are the frags. The double branch is up front.
