So, Rushell's been doing fine. He's been growing a bit and is very active. Extremely cute when he swims up and begs every time I walk by. But I've noticed that my tank is getting a fair amount of algae growth now. I don't own a filter as of yet, so I've basically been vacuuming the tank out with a tube every week or so? Is the algae something I have to worry about?
Oh, and unrelated question. I bought some cuttlebone for him, but he really doesn't touch it. How should I entice him?
