Well actually, I mean, it is figured in the way that the fish can swim under it like mangrove roots or something, and it has a hole in the bottom of it, and there is a hole on the side of it that is made to look like a real hole, and the on the top it doesn't close, it's completely open, so the fish can swim in it, that's what I mean. The reason I bought this piece of driftwood, as opposed to other pieces (not only that I love it) is the fact that others have tiny holes that allow water to come in, but are just a little too big that fish would get stuck in them trying to go through, but wouldn't be able to get all the way through, and get stuck.These holes are big, and the inside is made that the fish can't go down into the branching tangents, but it's hollowed out so it has a good swimming space. So basically I'm not worried about fish getting stuck in there, that was the overall goal when I was looking for the driftwood, and for 10$ it was a steal! What cool, is I was planning to ahve some glossostigma under it as a carpet under the roots to look really cool, but not enough light get's under it, so that's the main problem, I think I scratched that idea basically. Pictures tomorrow!
