picked up a really nice L190 the other day, about 3 to four inches long and really thick. He hasn't eaten yet though. I've tried algae wafers, zucchini, and broccoli, but I haven't seen him eat anything. He's gnawed on some wood but I haven't seen him take any of the algae wafers and hasn't touched the broccoli or zuc. It's only been 3 days but I'm worried it'll starve itself. Any ideas on how to get it to start eating again?
