You pose an interesting question, one with almost universal familiarity to those of us who breed corys.

I have no answers for you. Perhaps a suggestion to delay water changes is to attach a sump, 3x - 4x larger than your fry tank to filter the water.

Cheers, Eric

Fourth spawn today, occurred between 9AM and noon. Parents abandoned the pipe while I was doing a water change (I did not know they had spawned). This seems like a sloppy spawn with eggs more scattered than usual in pipe. I wonder if this was a new couple spawning. I haven't had good hatching so far...

Hi all, This citation is not current, so unworthy of posting in science "news". But I don't find much about this species on Planetcatfish, so worth adding: Eric, G., Moodie, E., & M. Power. (1982). The reproductive biology of an armoured catfish, Loricaria uracantha , from Central America. Environme...

Regardless of nitrate levels, he's caving and she's lining up for another go. I predict the 9th spawn by the end of the weekend. Time will tell.

Definitely a juvenile Brochis. B. splendens is the most commonly bred so I expect it's that. But someone was breeding and selling Brochis multiradiatus fry also, through Aquarium Glaser last year.

FWIW, I don't recall the differences between the two fry.

Cheers, Eric

I agree with your selection. In a personal note I would add the Corydoras Panda. But that’s just me and make it 11.

Yes you're absolutely right in the USA. I don't recall seeing Corydoras(Ln9) panda in the UK, but I'm confident it's common in the UK also.

Thanks!
Eric

Muchas gracias, tengo muchas fotos de muestreos de peces, en este momento subiré una con un bagre típico de la zona donde me encuentro, todos los peces que colecto son de la cuenca del Rio Salado del Norte. Thank you very much, I have many photos of fish samples, at this moment I will upload one wi...

I've been in only a handful of UK shops, but this is what I recall: In lineage order, then alphabetical, with commonly mistaken spp. paired, and may be offered as something else: Corydoras(Ln5) elegans Corydoras(Ln6) paleatus Corydoras(Ln7) aeneus (normal and albino are common) Brochis splendens Cor...

Hola soy nuevo en el foro, muy buenas publicaciones. Yo tengo un tanque de 10 mil litros con Pimelodus albicans. Vere mas adelante de publicar fotos de su crecimiento. Hi, I'm new to the forum, very good posts. I have a 10,000 liter tank with Pimelodus albicans . I'll see later on posting photos of...

Thanks for the advice. I'll see what plants are available.

I do plan to remove all the juveniles soon to a separate grow out tank, but right now I don't have that tank available.

Will provide updates later.

Cheers, Eric

Do you know if there is a convenient way to tell males from females or should behavior be an indicator when they are together to tell? https://www.planetcatfish.com/common/image.php?species=panaqolus_maccus&image_id=19895 The most obvious difference is that mature males become coated with odontodes...

Hi PicoPleco, Yes that is a clown pleco, probably L448 but could be Panaqolus maccus . They are very similar. All the stores I know sell them as Panaqolus maccus (when they are not grossly mislabeled). But I've read that true P. maccus are rarely imported but rather L448 is the common import. A grea...

Thanks everyone for a great convention, thought I'd post some pictures/video of some very large Chaetostoma which Pier had in, one I got a good look at, near the glass was ~10 inches TL some looked possibly larger. nunQr4BfnME According to Nathan Lujan, that matches Chaetostoma brevilabiatum . Cool...

Most likely a 40 * 40 * 40 cm tank. With a 0,16 square meters footprint.

I have no clue what a "smudge spot Cory" is, but I would assume you could keep some 20 4-5 cm Corydoras in such a tank, if these are the only fishes

smudge spot Corys = Corydoras similis

As Darrel stated, on paper the nitrates should not be able to reach such a level. The fish are doing great. That allows one, I´d say, to blame te measurement. Nitrate tests really expire after a while. So even this, rather convenient, conclusion is defendable. I would continue what you are doing. A...

Maybe elegans? I’ve seen them mislabeled as C123.

Possibly. Again, I hate trying to ID this group. LOL Great little fish, sucky IDs.

Eric

The first thing to say would be that we don't know what the safe level of NO3- is for the fish we keep Absolutely true. I'm really surprised in this case because both pleco species in here ( Dekeyseria and Pseudolithoxus ) are, as I understand them, high current, high oxygen, high water quality fis...

Hi all, We've talked a few times on here about how some of my tanks can have high nitrates and how that should be harming the fish but there appears to be no obvious harm. Today I bring you my toilet flush tank: A 40 gal breeder filled 1/2-2/3 full with a 50-50 blend of tap water and DI water. TDS ~...

Those two don't look like c123 to me. Are these wild caught or bred?

As an aside, this lineage is one of the hardest for me to ID.

Cheers,
Eric
