Sigh 

agree with above,but,id get a coconut and cut it in half,scrape the coconut out,cut a small v in the front of both pieces and add them both to the tank.maybe one at one end and one at the other.they can choose which one suits them best.
i'll never forget the time my pair spawned in a pot shard that was just there for decoration. there couldn't have been more than an inch of clearance at the mostit was so funny watching them swim in and out on their sides. the best part was that there had to be at least 2 or 3 un-occupied caves elsewhere in the tank.
