Seeing how I mostly keep the big guys I would tend to agree with you on the species angle. I have had a similiar experience with the palps though, big tanks with lots of cover and they do fine. In my experience the specs get grouped with the gators,Niles, salts, etc. I don't even use that much cover with hatchlings of the other species.

I always put food items on the bank with younger animals so it's easy to see who is eating what plus general animal condition. I almost never feed fish anymore. Like I said though in my situation they either get a big waterland or a 300 gallon stock tank and then outside they go.

Danny you have a female porosus correct?
