I had a surprise last night in the Erethistes tank. I saw this gelatinous object in the tank on the sand. I thought it could be an egg but it is MUCH too large to come out of the Erethistes. IDK what it is. It's about 3mm diameter.

Cheers, Eric

After reading the most recent description of a species of Erethistes (Mahapatra, BK & S Kar, 2015. Hara nareshi, a new species of catfish (Pisces: Erethistidae) from the Barak River system of Assam, India. Records of the Zoological Survey of India 115: 31–35.), which has a key to the genus (whic...

Here's the key to the genus Erethistes , which I extracted from the E. nareshi paper. For some reason the 2015 key is missing Erethistes koladynensis even though E. koladynensis was described years before E. nareshi . I've updated the key using current names, and I've taken the liberty to insert E. ...

And here's one of the Akysis:

Here's one of the Erethistes: 20241001_114336~2.jpg The information I have from the importer is this: They came by way of Thailand, as opposed to them normally coming through Singapore from India. I'm not sure if there's any reports of them from Thailand, but at the very least the catch location see...

Here's their tank setups:

Hi Joshuakahan, I'm not sure what that one line pim is... It looks more like a species of Rhamdia than Pimelodus . Side note: I visited the vendor's website and I see they list L015 Peckoltia vittata for $29 each, but the photo appears to be a mature male Pseudolithoxus kelsorum (although, if they'r...

Yes, definitely male, probably L052.

Hi Jake.

Welcome back! As for your fish, in my opinion, fish #1 is female and fish #2 is male. As to ID, I have no clue.

Cheers, Eric

Akysis microps has a truncate caudal fin. These look more like Akysis hendricksoni to me (assuming that they are caught in the same region as A. microps ). Thanks HH. Yes, that's the alternative ID Cameron gave me. I thought the tail looked too forked to be A. microps. I'll update the Akysis pics a...

This weekend I was at Fishtoberfest 2024 in Portland, Oregon. After visiting the Wet Spot fish store, I picked up ten each of what were imported as Akysis microps and Erethistes jerdoni. Although the Erethistes is a common import, Cameron at Cichlid Exchange pointed out that their color seemed diffe...

Spectacular!

Here's an update on the 33long. I've added Anthurium and a big Calla lily, and I've removed the blue foam block that was suspending the kinon plants and restructured the plants using corks, bamboo kabob skewers and woven coconut husk:


Revised floating kinon raft in 33long tank

For ease of comparison, I took your last two photos of the faces and put them side by side. I also flipped horizontally the image of the "common" one so that the two heads are angled approximately the same. I hope this is helpful.

Cheers,
Eric

Thanks. The fish has no obvious coracoid bones, so I'd agree with Callichthys, not a different genus.

Could your fish be a different species of Callichthys? I don't know, but I'm not aware of other species being imported.

Cheers, Eric

Lastly, the huge draw back of an air system is that it is a single point of failure for the fishroom so you will need at least one extra on hand as a back up. That drawback aside, it is the cheapest, easiest way to run filtration in a small to medium fishroom. This reminds me of my friend Carlos in...

Hello @aotoo.

Can you get more photos? Good side view photos and also photos of the abdomen, especially the pectoral girdle?

Thanks,
Eric

@DBam, Since I don't yet have my own fishroom, I can't offer specific advice. But I can agree with the others who've mentioned standardize the sizes of your tanks as much as possible to best utilize your space. Go with low height tanks if you want to even try for a 3rd tier (e.g., 30 breeders at the...

Without knowing catch location, we can't tell the difference between real P. bufonius and P. cf. bufonius. The meaning of the "cf" is "conferred as." In other words, without additional information, they look the same.

Cheers, Eric

Thanks for your labors.

Hi Jools, I just renamed Hoplisoma similis to Hoplisoma simile . The operation sends to have been successful, but I got this error message afterwards.

This might be the first time I managed to stay at work late enough to see the daytime white lights go off and the red night lights come on, while it's also dark outside. Fun to see the Tatia intermedia pop in and out of view. The bright glare top right is a floating egg basket connected to an egg fu...

Do you already have any medications on hand, or are you looking for something new to try? It's been over a month since the last post. I imagine these fish are either cured or dead by now. Did you have some new medication in mind to suggest? I'm sure people will have diseased fish in the future, so ...

There are some great videos on automatically collecting Celestial pearl Danio eggs, if you have not seen them they are similar to what you are doing here. Good luck with this, will be interested to see how it works. Thanks. I'll check them out. I've also seen a few setups to do this. I do see video...

I added a vaccum-powered egg trap tonight to the 33-long. This is 3-D printed by Lowell Dunnaway and it feeds any eggs collected into one of his 3-D printed egg baskets. One negative issue with the egg trap is that it has too much space underneath its legs, so fish may spawn under the trap. But fing...
