Does anyone have any experience with them. I have mine for 2 weeks As soon as 6:30 hits he lays up against the rocks in my tank it is now 9:40 he still ahsn't moved his lazy butt I also have never seen him eat yet he is still alive. Do they eat at night his teeth look worn down so maybe he is sneaking snail snacks at night. I alraedy know he is not reef sfae he is just too cute to resist
