My understanding is that except for girth in gravid females, the reliable way to sex is comparing genital papillae. Sexing is good to know for curiosity sake and naming (if you name your fish), but of course, these big fish haven't been spawned in aquaria, presumably because of their habit of burro...

Hes here, or she I don't know how to sex these guys.
But definitely pardalis I think.

One photo does show slight under, I see spots, rather than reticulations, so I will lean towards pardalis there too.

Reallllly hoping of those, he's pardalis haha Hes only about 11-12" counting the tail, several years old as well. I'd think if disjunctivus he'd be larger... But I'll take a look at the belly view once we have him to confirm and pray he's not gonna get larger hahaha. He will be joining my 6 foo...

A coworker is rehoming her pleco, asked me to take him in. These are the photos she sent. I thought gibbiceps when seeing older photos, but these photos look maybe more like another of the commons? No belly photos available yet, but when I get him I can take some better photos of his belly, measurem...

Was wondering perhaps P. Britskii based on the blotch pattern, dots on the caudal fin, and the way the saddle marking bleeds into the base of the dorsal fin.

Fairly sure that's this species of "common" but yes is not a rubberlip

Scrap the bloodworms. Use mysis shrimp, brine shrimp, daphnia, or cyclops. Of those, daphnia is actually fantastic. Do you have photos of their barbels and of the substrate? How often is the substrate vacuumed? What's the flow rate of the tank? Wondering maybe if there's any dead zones in the tank t...

My own two cents is not to put them in as a known described sp. I would add them as Ancistrus sp # and note the trade name they were imported under and that they may be one of the described spp from that drainage but we can't make offer a definitive identification without verified provenience infor...

Jools

The other one was the female.

I've added these pictures, with a degree of discomfort, into the Ancistrus martini entry. The belly patterning bothers me - while patterning is sometimes initially emboldened in preserved fishes, much less so on soft skin. I could add a note to these ones noting they are closer to the description o...

Had to move my pygmies in with the eques, they had an incident in another tank with my skirt tetras eating one, so felt safer to move the pygmies into another tank. So they have pygmy cories as tankmates now. Getting along fantastically and the pygmies seem really happy with them 20211015_152018.jpg...

But how would I attach it in the substrate if not doing that? Currently have it floating but to be honest I think my circulation in the aquarium might be abit strong and it doesn't look to hot right now, might try to attach it to some branches or whatever with your method or just cable ties, I also...

He has settled in, hes way less shy than the female is as well. 20211006_202915.jpg 20211009_213920.jpg I have to say, I love the way the texture on the skin shines on these guys. Makes them almost look gilded with gold. They're "plain" at first appearance, but are subtly really beautiful ...

Okay! I don't really understand what part of it is the stem and what's not(the plant is not in the best of shape so that doesn't help) ill have to check in the morning once lights are on. Maybe ill just try to attach it to something like you did! If in doubt, let it float, see where it starts growi...

Gonna try to get more views of him as he settles

Male acquired!

Great looking tank, is that pennywort to the right? (I know close to nothing about plants but it looks very good! :) Yes indeed, hydrocotyle leucocephala, aka Brazilian pennywort. Great plant! I've got it secured on the driftwood rather than planted and it does great Good thing I was right for once...

. So given that it's been merged with a. Martini, can assume that beckateen has it correct then? I do not agree that A. bodenhameri is synonym of A. martini. I went back and read the Trans Andean paper again and am even more convinced after reviewing their reasoning. Your second point (the market i...

Original description A. bodenhameri. Compare to your fish as she settles in. -Shane So given that it's been merged with a. Martini, can assume that beckateen has it correct then? The description is pretty spot on. Dorsal does have a pale tip restricted to the first 2 rays, causal does as well. Dull...

On the positive side you found something neat. On the negative, it is probably just one of the dozens (perhaps 100s) of undescribed brown Ancistrus spp in the Andes. Galvis et al (Peces del Catatumbo) show a fish very similar to yours and label it A. triradiatus, which is incorrect as this sp is fr...

Awesome then! Hopefully my L240 doesn't mind a neighbor in his tank. Going to assume it will fare best in 76F-80F range given if it is those species, they come from a warmer area, so probably a safe bet to keep her higher 70s than in a cooler tank then

My fish

Add after your edit, fish in the underside photos in store are of different individuals. The wider mouthed one looked more female to me while the other certainly had more bristle coverage classic with a young male. But one does have spots, the one I brought home does not. I will get a belly/mouth vi...

Hi Miss Noodle, Here are your last 6 pics, all laid out with same orientation and scaled to help viewing. Looking at the fish, and seeing the spotted pattern, this is certainly not Ancistrus sp`cucuta` . It is more reminiscent of Ancistrus martini , which has a spotted body and a wide head. That sa...

Acclimation and size reference.

Cucuta, which is a town on the Colombia/Venezuela border, seems like an oddly specific common name for a store to use. There are several brownish Ancistrus recorded from drainages in that area. I would take a hard look at those fish. -Shane I went back, got some more photos including belly shots an...

Short term should be okay, but watch for signs of trouble, increase oxygen, and change only gradually would be my best advice. Short term "heat waves" happen, but no matter which option you choose there are risks. Personally, for ich in the past, I have gone a half strength dose with Malac...
