Sorry about that, It's getting cold up here! I'm preparing for the winter, lots of nuts to store.
So, we have a new "Taxi driver" in our midst. Happy days are here again ... and he has a pair of newborns to boot! (He) meaning you 'cause I'm responding to Piersons' "where did I put that boy?" call.
OK, my browns are about 2 years old now, approx. 14"-15" long and still quite slim though the female is clearly more bulking than the male. As Pierson has stated, Browns are baskers and primarily (if not entirely) piscivorous.
NOT INTENDING TO CONTRADICT MYSELF ...
My observations of a captive pair; newborn to 2 years:
a) primarily nocturnal OR very secretive as youngsters.
b) do bask in branches but have retreated when I'm seen.
c) recently basking more openly, the female in particular.
d) will accept swordtails, minnows, big guppies, goldfish and whole frozen/thawed trout also trout strips.
e) seem to prefer food in the order above. (trout is usually offered on forceps and is taken a little less "forcibly" than live fish.
f) I have not had the opportunity to offer them catfish however, I'm truly confident that these would be the food of choice!
g) they have "snapped" at me once or twice but have never bitten me. They're calm once picked up but occassionally go a bit snakey if restrained.
I suspect that I may not be providing them adequate height for their liking since there is so much documentation including Piersons' field reports/photos to support this habit. In all likelyhood, due to their age/increased size/confidence they would "transfer" to perches duing the day rather than hide if/when I correct the set-up to "outside river bends, sloping access to the water with adequate perches". This is paraphrased from a research paper on Taxispilota that I read some years ago.
Wow, I just made up for six months off-line in one response!

By the way (Pierson), those mangroves have doubled in size!! Also, that one green in particular shed two days ago to expose the sore - which I thought was just about healed - not! Have not, but will get and try, sulfazine.
