I have had my Hemibagrus wykii (8.5” when introduced) in with my two sub-adult Channa micropeltes (large one is 14”, smaller one 12.5”) for 26 days. A few times I have heard thuds and splashes during the night, when the wyckii has been “out and about” but nothing drastic in terms of damage to any of them, I have noted some flank damage to the micros and a small split in the wyckii tail, which healed up in two days. Today I was removing several rocks which formed a cave for the wyckii at one end of the tank to put a large semi-circular pipe section in to give him more room, as he eats even more than the micros and is now 10.25” v. 8.5” in 26 days, with A LOT extra girth. I was interested to see how he would react when I removed “his” rocks before putting the pipe section in.
Firstly he bit me twice, then went along to the end of the tank where the two micros were. They both immediately turned very dark in colour before the bigger one had a bite at him, with a rasping sound.
The wyckii then flexed his body, turned and bit BOTH the Channas with a loud thud and held his corner without fear of the two micros flanking him. I have had one before but I tell you this guy has balls! There is an uneasy truce. I do note that some things that still spook the Channas, movement in the tank, lights going on/off, glass cleaning do not bother the wyckii in the slightest.
I think both species are great but I think I am in for very few dull moments in the next few months, even after they go from their present 6 foot tank to a 290 gallon in August. Im very pleased with the wyckii, great colour, girth and fins, with long trailing white edges to the forked caudal. Hope you like the pictures!!!

I have seen pics of wyckii's bitten in half by big Micros. Those teeth are made for slicing :(

How big do you think the wyckii will get in your big tank ?

All great looking fish.

I've seen photos of small ones in half, in the 6"-9" range, but once over 16" it would surprise me, I think he shall (hopefully) make it to 28.5"....

Yeah, I think we may have seen the same sad pics.

He is a good size as a match at the moment though. It's just as those teeth get bigger??

What are the Wykii's defenses like and it's teeth, how hard is it's fine/spine armour, has it got any? I have no experience with them and yours looks really nice. If it can survive two micros who have attacked it, Pleuros would be a push over.

They are naked, but with strong, sharp pectoral spines. They do not have any teeth within the lips, but like many large predatory catfish they have both Pharyngeal (throat) teeth and I believe also vomerine (roof of palate) teeth. As they occur in many areas that many species of Channa do (inc. micropletes) they are formidable predators. Apparently they predate on large gouramis, barbs, other catfish, knifefish and small and medium snakeheads! Their bite pounds per square inch is immense, there are reports of one crushing the head of a large synodontis to paper thin proportions before swallowing it whole. This power especially from underneath can easily disembowel a fish, even a large one. So they do not have the dentition of a micro but have immense power. I must confess I would not have one dedicated to a large tank alone, they look great, and are good value at feeding time, but relatively inactive. I do not buy into all the hype about them being "home alone" fish either. I know three people that have had them in very large tanks, with large fish (not bottom dwellers though obviously) and they were fine. They were also acclimatise to other fish a young age too though. Both it and the micros only get heated up when either gets too close, otherwise they are fine. It could end in tears of course, but that is always a risk. Which do I value more? I REALLY like both, but if push came to shove it would be the micros.
 
i would be surprised if your wykii didn't kill one of your micros before they all got bigger! All gorgeous fish though i hope they get along in your bigger tank
