Fabio... aka Spot, is getting a tank ornament / hiding spot and silk plants on Tues. He had torn his fins already and though I know I can not totally prevent from happening I'd like to try and reduce the chances of it happening. What are the best ornaments in your experiences? He's an extremely happy boy (I think) and very friendly and I want him to stay that way. He built me a HUGE bubble nest, the biggest I have ever seen. It towers about an inch above the water. It is a bubble mansion. It is going to break my heart to do the next water change.
