Hi YFS, Corydoras sodalis often show up at LFS but are sold as something else (another cory species). I've seen them for sale as Corydoras agassizii, Corydoras reticulatus, and even Corydoras julii. Usually they are priced around $7 USD each. Keep checking out your LFS and if you can time it right, ...

I'm sorry for your loss. You don't expect something like that to happen over just a 3 day weekend. Do you have an idea of the cause? Thanks. You're right. I didn't expect it. As to causation, I suspect a stoppage of sufficient water flow/aeration. This tank is about 40 gal. It has a Matten driven b...

Corydoras(Ln8sc3) sodalis.

Cheers, Eric

Horrible update: After nearly seven years, I lost my entire group of Hemiancistrus guahiborum over the weekend. I was away for three days and came back to a tank of dead fish. I lost all eight H. guahiborum , plus my last Centromochlus orca . :(( :(( I've had some of these H. guahiborum longer than ...

The fish appears to have body spots and a spotted tail. CW045 has unspotted flanks, but I see lots of spots on the sides of your fish in these photos. If your fish are a short snout species, I'd go with Corydoras(ln9) brevirostris before Corydoras(ln9) melanistius , which has almost a hyaline tail o...

Then it is the camera angle and I'll stick with a washed out C. sodalis.

Thanks Dave.

Welcome to Planetcatfish! Both pics show fish with faded colors. They need to relax and brighten up for better ID. Second photo is probably Corydoras(Ln8sc3) sodalis . First photo looks like a different species (although maybe it's the camera angle), probably a lineage 9 cory. Better pics please, if...

Bottom looks like a clown pleco, Panaqolus maccus or L448, although the eyes look big for a clown. Do you have more pics?

Cheers, Eric

Hi AZBetta,

Welcome to PlanetCatfish! Your pleco is definitely not Peckoltia compta (L134). Your fish is one of the Hypancistrus species, although exactly which one I'm not sure. Do you have any information on its source?

Cheers, Eric

Looks like Corydoras(ln8sc4) agassizii to me.

Cheers, Eric

This is a question I get from a lot of cory keepers. I've never been good with meds, so I hope this paper is helpful.

Using metronidazole and albendazole to treat nematodes in Corydoras virginiae

I also hope you read Spanish.

I've been keeping zygatus, ambiacus and c156 in a standard 75 gal since 2019. Same depth as a 55. You should be okay.

Good luck,
Eric
