Different species. I have a blue whale catfish. Cetopsis ceocutiens. Not blue catfish like what you find in a river. But I’ve never seen a 150lb blue cat nor have I seen one fast 4 feet. In person I’ve only ever seen a 60lb 3.5’ blue cat.
You may have already come across the information but Planet Catfish has them growing to just over ten inches.

There used to be a few post on cetopsis here. The purple ones are sweet. Get a few more if you can, it’s great!!
I don’t have room for any more of them also they’re so rare that I don’t think I could find more if I did have the room. I’d love to have like 7 of them in a big tank. What purple ones? Can you show a picture please
 
There’s 10+ pages of info if you type cetopsis in the search bar! They used to be really popular, till people figured out they kill everything in the tank and I don’t think they lived to long in aquarium settings, unfortunately. Read some of the old post, they’re very informative. I think I even started a post way back when.

How do you suggest I do a gravel siphon without Cookie Monster tearing up my arm? And before someone says it. No I’m not able to just hold onto the small tube and move the siphon around, it’s not as accurate as holding the siphon part (don’t know the actual names for it but the siphon part is the larger tube).

Get the water level low enough so ur arm isn’t in that tank. Other option is get the larger gravel vac that has the longer cylinder tube.

Thank you. Somehow I Didn’t think of lowering the water level. Reason I ask is because this fish has tried to shred my arm up before and I’m genuinely terrified of having any body part in the water with him
