So the vids didn't work for me, but regarding you asking where they're caught and why they get caught in shallow streams, my guess is breeding as you said. Because of this I don't think their main diet as stated would consist of birds or mammals. I think naturally they are piscovorous. Most riverine predators are due to not may species being able to live in the same environment in large numbers so often that's why riverine species are very territorial due to lack of food and eat what they can get to, usually fish.

Regarding dloks ID guessing by the size of it you may have purchased it around the time where Wes labeled every cf. lac which only meant it was related to lac but he didn't know the species. Looking at that pic I'd guess Australis. We haven't seen a true lac in the u.s for quite some time.
Let's for example focus on piscivorous fish. Fish is easy to digest. It's a weakly connected tissue with different protein make up, soft bones, almost no ligaments versus a land / air animal that has to cope with gravity. Also you need to cook fish 10x-100x shorter times than an animal of land or air and even after that one needs a sharp knife :) Usually not so with fish - the flesh falls apart and "melts" in your mouth.

Anyhow, this is about feeding mammal or avian meat to fish. Protein makeup and ease of digestion are of secondary concern. The fat is of first concern. It turns solid inside a cold fish body, while it was liquid inside a warm-blooded animal. Solid fat cannot be well digested by fish and is deposited in body cavity and around internal organs, eventually harming them.
look who makes an appearance :) I was gonna tag you but felt I keep dragging you over here didn't wanna bother. I know there's been talks of this in excess over in the cat forum so I knew you would be perfect for it, guess I should've tagged you anyway lol.
peter predtank peter predtank here you go Peter I'll take a better side profile later. kno4te kno4te yah I know even Wes himself isn't certain. I'm happy with my wolf honestly most personable fish I've ever owned. Swims up to the glass to eat always active. And believe it or not he thinks he's a bichir

Ime wolves and bichirs are long lost brothers lol I've always had them behave best with eachother.

Peter great discussion you bring up regarding mammals being fed. I'd have to side with the other guys in that feedin it so much may have long term negative effects. I do agree they eat them in the while but only on occasion so it has no effect. But maybe you're right. Who knows really. Wolves need to be studied better to be certain. Anatomy and habitual behaviors etc.

Now I think three pages is enough derail for nzafi unless he doesn't mind lol

Yes Sorry for the derail nzafi hope you dont mind i just love talking about these fish i find them fastinating and sence you do as well :)

To bad you couldnt see the video links i posted moe it really is interesting.
As you say also if these fish do get caught in these reciding bodies of water , after going there for spawning . and then caught there till the rainy season comes again for them to return to the deeper rivers the food in the form of fish could become scarcer., perhapes then they would eat more mammal food items .

there is a part of the videos i liked that says the native peopme there have seen these fish jump out of the water to grab monkies. And also one person says they were attack whe walking across a log .

i can attest to mine trying to take a chunck out of me a few times by jumping right out of the water at me . also im sure if i put a branch over the top of my tank with no lid they would jump to get a mouse crossing ok enough derailing from me unless nzafi doesnt mind

Just curious did you guys read the article i linked about the trout and grayling? Interesting no doubt ? The wolf would be much higher body temp then those fish also . to me though that would just mean faster metabolism . but then again the fish would also adapt in this regard just by evolving in different temp environments . meaning the trouts metabolism may be the same speed as the wolfs in a colder temp

also fat is not liquid in the form it is on the prey items body . it may well be turned into a liquid when broken down by the digestive acid . but looking at it as a substance that is going to harden in the fishes body just because they are cold blooded doesnt make sense really . and the article i link would prove this other wise all those trout and grayling that apear to love the furry little shrews would be floating belly up from clogged arteries lol
how would cold blooded animals like alligators and snakes especially ones from colder climates . manage to eat warm blooded animals with this logic
Did read it. I think it's an interesting article.

Well since it isn't much of a detail but rather me reciting what I said earlier, larger wolves are known to go on hunger strikes in captivity for months at a time up to half a year in my personal experience with not much weight loss, must be a habit from the wild one would think in cases of food being scarce, because food is plentiful in captivity and they have no reason to do so one would think. But your theory is plausible as well. As far as what native people say, take it with a large grain of salt. While I'm sure wolves jump and certainly have the ability to bring powerful swimmers I'm not sure about grabbing monkeys, I'd think their jump would be to slow. The only real attack I believe told by any natives is micros when spawning and only if the pair is exceptionally large. But that's just me. Like all the stories on river monsters. I took those with large grains of salt.

I don't think he'd mind us talking about their feeding habits etc but we derailed when we began talking about how feeding mammals effects fish in general etc so I wanted to hear away from that personally. Catfish section there was so many of those convos.

All good info folks, so no worries provided we dont go 10 pages of derail. Ultimately I plan on keeping this thread updated for a long time.

I am going to go to my local chinese market to see if I can pick up other small aside from silversides. I want to get him variety and I will see if I can stuff pellets into the food. I just need to have some patience. Keeping a rhom for 17 years and squeezing barely 1/2in a year you would think I have some patience.

I plan on uping the drip on my tank. In all honesty I wanted to upgrade my tank summer of next year but might need the 180g to stretch longer than that with all of my costs related to new baby and new house. It might be better if he slows down on growth.

Just my quick opinions, Peter. Take it light-hearted. No time to type a manifesto that'd be thorough, scientific, ideally courteous, and impossible to misinterpret.

Nzafi, my friend, I apologize.

Peter, if you wish to continue, please, make your own thread on the topic. I cannot stand derailing this any further.

**********************************************************

Just curious did you guys read the article i linked about the trout and grayling?
*****This is from 2013: https://www.monsterfishkeepers.com/forums/threads/yummi-shrews.554628/#post-6616353

Interesting no doubt ?
*****Of course.

The wolf would be much higher body temp then those fish also .
*****A few degrees Fahrenheit is not much. In any case, warm-blooded animals body temps are 100 F and more. Our pets body temps are close to or barely above that of the water they are in, which is usually 75-80 F.

... also fat is not liquid in the form it is on the prey items body .
*****You're right. It's in one of the great many forms of an amorphous state, which transitionary between solid and liquid. It doesn't run though.

it may well be turned into a liquid when broken down by the digestive acid .
*****Agreed. But I believe fish digestive system are small-powered, primitive and weak relative to many others.

but looking at it as a substance that is going to harden in the fishes body just because they are cold blooded doesnt make sense really .
*****Why? Perhaps if you get bogged down in details but generally it describes the situation rather adequately at first approximation and to the level most people readily grasp.

and the article i link would prove this other wise all those trout and grayling that apear to love the furry little shrews would be floating belly up from clogged arteries lol
*****This was an accidental meal, my understanding is. Moreover, one article proves nothing. There are thousands of scientific articles describing deleterious consequences of feeding mammalian and avian meats to fish.


how would cold blooded animals like alligators and snakes especially ones from colder climates . manage to eat warm blooded animals with this logic
*****Simple. These animals don't remain in water after a meal. (They don't feed in cold times of the year either. Snakes hibernate. Crocs meditate :) ) They get out onto warmer air and ground and sunbathe and reach quite high body temps to help digestion. Black gators sitting for hours under a strong sun probably are as hot to touch as parking lot asphalt! :) Besides, their digestive systems, esp. those of crocodilians, are supreme, with pH reaching 1.0 and lower. They can digest horns, hooves, and beaks, and also fur and feathers that many mammals and birds cannot digest and have to cough up :)

My understanding is that snakes also boast very high acidity and powerful digestion.

*********************************************

I am sure nutritional powerhouses in residence, such as RD., Oddball, and Co would have most valuable input and would vastly correct or disprove my statements.

Lol seems like the rhom drained you dry of patience and well I believe you will see a decrease in growth after a little over a foot. 12-18" range.
