Hi Magnum Man!

Welcome to Planetcatfish! When you have some time, please share about your catfish.

Cheers, Eric

Cessation of spawning aside, the fry from the six spawns are doing great! I suspect I have at least 400 babies growing out. I'm moving them to a 40 gallon tank soon. The Ziss breeder box is way too crowded.

Cheers, Eric

Sadly, the pattern has broken. I did a water change on 25 February. It was the first WC since before my 10 January spawn. I wondered if that would either trigger the next spawn or alter the water quality and stop the spawning. Maybe it mattered; maybe it didn't... but the result is no new spawn. It'...

I've put 10 C. sterbai in a tank that size. It can be done if you keep the water quality high. But it can also be a fragile balance and is at risk of water chemistry changes if you don't keep it stable.

Cheers,
Eric

Hello,

I'm not entirely clear on what you're asking. Are you asking if the two species can be told apart as juveniles? Are you asking if they'll grow to look the same as each other when they're adults?

Cheers,
Eric

Looks like delphax to me.

Pics today of one Pseudopimelodus aff_bufonius in tank (the usual view I have of them) and of another individual, caught randomly. The latter is 13.6cm SL; this fish is "random" in that I did not attempt to catch the largest fish, although I think it might be the largest fish. If you compa...

Thanks so much I will definitely get some of those! Looking for a ziss style that is huge for attaching to some of my larger tanks. The tanklimate holes are to big. I've got over 200 Auchenipterichthys coracoideus in my Ziss BL-2. The babies are getting big so I need to move them to a bigger home. ...

Congratulations on your spawns! No, it's a standard Ziss BL-2. I chose it because it has a solid floor, which provides two benefits: 1) it prevents microworms from falling out of the box (a problem even with the fine mesh of the German breeder rings) and 2) when you drain the parents' tank for a wat...

Lol. Indeed, bamboo stinks as it soaks, but it's so good as a spawning cave or hiding place. The worst wood I ever tried was an old grape vine ( https://www.planetcatfish.com/forum/viewtopic.php?p=299723#p299723). It developed a horribly smelly thick slime. I was hoping the L397 might eat the slime,...

It appears that all the eggs fungused.

Hopefully the adults spawn again soon, this time releasing fresh eggs.

Cheers, Eric

For a fleeting moment, I thought I had the Norgum River solved, but no. I found two publications about invertebrates, each collected along the Norgum river below a specific village. In one case, the Dengzi Village. In the other case, the Betchilling Village. Combining those two references with the C...

Second clutch of eggs hatched and the previous group of fry are doing good. Not surprising, but somehow there are a few of the older fry loose in the tank too. Either dad let a few get away from him, or else a few managed to escape the German breeder ring.

As I added this new species to the CLOG and endeavored to create a (hopefully) accurate river system to near its location, I noticed a minor discrepancy in the type locality as presented in the paper. I think it's probably insignificant since most GIS data have a margin of error, but I'm not totally...

For the first time in a long time, we have another spawn of the Microglanis aff_poecilus . This time though, it's my first spawn from the Rio Nanay population (all previous spawns, in none of which the eggs developed, were from my Rio Blanco population. Most of the new eggs today look bad, which is ...

Hi Jools, Today I tried to rename Platydoras cf_birindelli to Centrochir cf_birindellii . There are currently two problems with this name. the specific epithet is spelled incorrectly (it needs the double "i") the real species ( P. birindellii ) has been reassigned to a different genus, Cen...

Agreed. It's now gone.

Thanks, and good luck with your contractus.

Cheers, Eric

Agreed. Perfect timing!

Looks like it's fixed! Thanks Jools!

Hi Jools,

Super-low priority, but I thought you should know the touch pools are no longer functioning.

The dorsal view of your L397 does appear to have small odontodes, so it might be male. 9cm is plenty large to show sexual traits.

Cheers, Eric

The only L397 shown looks female to me, but if it's immaturethen could be male. My inclinations on the Hemiancistrus are all female based on pectoral odontodes alone. Which L476 is supposed to be the male? The small one? I do see the head shadow differences... again, maybe the smaller individuals ar...

All newer numbers you should be able to track down by the post dates of Tyner announcements on Facebook or on the CW website. But older ones might be difficult to pin down. I wish you success!
