Ultrasoft Clearwater Livestock Options for Male Panduro

Hello all,

I recently bred what I believed to be a sibling pair of A. Panduro A 183. These are the common A. Panduro lacking a striped pattern on the caudal fin. A few males expressed long black caudal spots, one of which I took as my prize for the labor of raising -- the rest I was able to sell. Patterns on the females were more diverse than I thought, with some having large, connected ink splotches reaching the belly, and some others having disconnected ink blots. Age seemed to expand this spot for females, and the juvenile males I found for it to retreat into nothing -- revealing the silver/grey and blue hue found on the rest of them. All juveniles expressed that midbody black mark, interestingly. Parents were removed at about 3-4 weeks. Male parent played a caretaking role in the first week by guarding the spawn site and school while also grabbing and relocating by mouth like female. After some time, female parent became more aggressive towards male. After about 1 month, both parents were removed.

In all, I had about 50 fry that I was able to sell from a single go. The only losses I had was a 1" male that I may have prematurely removed and put into my tea-stained Orinoco 20 gallon where he resided as the sole Apistogramma among some Paracheirodon axelrodi and a variety of Rummynose tetra that I was unsure of. He escaped a couple of times over the course of 48 hours, but we were unable to catch in time. Parameters were very close to its breeding tank, about 80 TDS, 6.7pH, and 78F. I had another spontaneous loss of a 3/4" male in the breeding tank.

The lot were a little unimpressive from what I've seen online of other A 183, and I worried that I didn't provide the correct food, diet, or environment for them to completely develop good coloration. Temperature ranged from 75-79F over the months, and the M:F ratio was about 1:3

I am moving up to another show tank, a rimless 36 gallon.

I intend on using an acid buffering pellet aquasoil and a planting scheme that most here won't find interesting enough to share.

I am seeking some suggestions on a more uncommon monomorphic tetra to stock, particularly under 6cm.
I will be keeping some of the Paracheirodon axelrodi, but would like to introduce another Hemigrammus type tetra.

I have found Tucano Tetra (Tucanoichthys tucano) from Peru, Peruvian Tetra (Hyphessobrycon peruvianus), a similar looking Characin to the Tucano, and lastly the Loreto Tetra (Hyphessobrycon loretoensis), which is found much further north.

What I find attractive is the strong, black line with yellow coloration.
I believe the Tucano Tetra may prove to be expensive and difficult, as I won't likely achieve a necessary pH below 6. They are also rather dimorphic.
The Peruvian Tetra appears more robust and in line with the torpedo shape I am seeking, and has the added bonus of being monomorphic, something I really find attractive.
Loreto Tetras also share some characteristics with these visually.

Are there any other suggestions? I have also found some appealing variety of Penguin tetra, but they appear a bit too large for the setting.

Attached are images of the A. Panduro batch. I would include the tetra I am considering, but I do not have any common permissions to share.

Best

Unfortunately the local fish store's lighting washed most of the color out in the above image.

Only one remark: I find soil to expensive and not useful for use in softwater due to its properties.

After reading I'm a bit bewildered by your aims with the pH. The ec is the most important parameter and 2ith your EC and TDS readings the pH is almost irrelevant. If you are patient enough leaf litter, botanicals and additional hunic substances can bring down the pH to 5 safely. You just have to be ok with it taking 3 months to get down there.

What are my aims with pH? I haven’t mentioned any aims other than some slight acidity. How would I achieve a clearwater tank with litter and botanicals, that doesn’t make sense to me. That’s what my black water tank is for.

I've been happy with ember tetra; they are not cheap ($10 at many locations) but not super expensive either. There is a blueberry tetra. Personally i prefer (as i've said a lot) n. marilynae which are nice and small and relatively cheap.

If you want something exciting n. epesi but they are of course 6x more expensive.

Love the tucano tetra from Brazil (Tucanoicthys tucano), fantastic dither, and small enough to not bother fry. I’m not sure I’d describe them as dimorphic, I can’t tell the boys from the girls, but there are alway fry. The blueberry tetra (Hyphessobrycon wadai) is absolutely spectacular when the males are excited, absolutely sexually dimorphic fish, and an epic fry predator.

I might have phrased it wrong, sorry. You mentioned to get problems getting the pH down to 6 if you went for Tucano tetras, which is neither necessary (as I mentiond EC is key) nor impossible. Leaf litter an botanicals are not a peculiarity of blackwater habitats. You find it in all softwater habitats from whitewater varzea forests, to clearwater morichales to blackwater igapós. True blackwater is almost unachievable in aquariums, so basically all softwater tanks may, at best, end up in the (higher value definition) clearwater range of EC around 20 and pH somewhere between 5.0 and 6.5. Per scientific definition clearwater primarily shows an EC of about 15microS/cm and only secondarily pH around 6.
pH is not a primary factor in the definition of softwater types, it's just EC.
In the end I just wanted to shift your perspective on the definition of the water typology. You seemed to be focused on a factor that doesn't matter, actually.

Me neither. In stained water it's almost impossible to distinguish, in uncoloured water the metallic sheen is a bit more pronounced in what could be males (never bothered sexing them when I had them).

Not sure why i wrote ember; i meant morse code tetra.

Hi I didn’t know if you still have any of the Apistogramma Cuipeua?
Would be interested if so.
