Centromochlus perugaie are a teensy little wood catfish from Southern America that live in clear, fast flowing streams. For a while I kept them in an 8 gallon tank using a strong internal filter to make current, but I found space in a 15 gallon and made them a little haven. Since they are shy, here is a photo from yesterday when I kicked their wood about a bit:

I only have 3 of my original six I purchased about two years ago, have bred them once now in lockdown before the move but my brine shrimp hatches failed and I lost the fry. Anywho, they have a nice new tank like this:

But now, 3D printing you say? Yes! I wanted to make a unilateral flow system (like a hillstream tank) so using an old pump, tubing and 3D printed parts I created the disgusting looking pipe system in the tank. With help from my younger brother we made an adaptor for the canister intake cover as the pump quickly killed one of my female catfish initially, they like tight holes. Big mistake from me. From there we reduced the pump outflow to the beige pipe which runs along, turns at a 3D printed elbow then runs up into a printed spraybar. I placed the pump really high up so the catfish wouldn't try to hide under it. I detailed the tank in a quick video:

The parts look something like this, I didn't take more photos during setup unfortunately, in varying colours. It is ABS plastic, same stuff they use in reef piping, and I have used it to make caves and other various items before. Pretty cool to have a designer brother handy.

This is just a quick post to highlight how useful 3D printing could be for the hobby!
 
Those are beautiful little catfish; not much info available on them that I can find. Google led me to one video: yours!

I must say I'm a bit disappointed; I was hoping for instructions on how to print the catfish. I was going to have my granddaughter print up a school for me and then try to breed them. I really like the design of your stream tank, although I'm not sure that any of those pieces you used needed to be printed. My technique of walking up and down the plumbing aisle in Home Depot, furrowing my brow and going "Hmmmmm..." usually yields whatever oddball little bits and pieces I need to cobble things like this together; I suppose the printer lets you do it more easily now that social distancing is a thing. :)

Nice job, well thought-out!

They are a bit niche, I think O'Leary did a video on them. Very cute too

It would be cool to be able to print fish, maybe some ornamental ones are in order. As for fittings, we don't have such a selection here in SA and I was under full lockdown at the time so used whatever scraps I could snatch from the garage and used the printer to accommodate that ;)

thought about getting honeycombs, very nice little catfish. very cool!
 
I took the setup out, since I added my kuhli loaches to the tank, one of which promptly blended itself so this is shut down for now. The catfish are still adorable though!

do most/all wood-cats prefer faster water?

I've got a set of zamoro (5) that are a little timid since moving to the 50, was wondering how I might bring their happiness back up.
I was thinking to renew the 100 as a do a flow system for the loaches - if I could also have the cats in there also, that'd be grand!
