I don't think I'm quite happy with the stocking in this tank, and I'll eventually change it.
Ah, so it is longer. And shorter, which makes it look much like a 125. What about the stock don't you like?
From everything I've heard and read, the Rio Araguaia Orange Heads seem to be much more temperamental with their orange than the Tapajos variant when kept in communities.
Interesting. I had not read that. In fact I would've guessed the opposite, at least judging from how good all the Araguaias I've seen in photos have looked. Does that reading also include any way to tell the two variants apart?
I feed the same stuff as you and one pair of my orangeheads has no orange at all. They used to, when I got them, and when they tried breeding repeatedly, but around the summer they lost their orange, stopped trying to breed, and took on a darker, bluer tint overall. The addition of the 2nd pair didn't help their color, and the 2nd pair got a bit duller as well for a while, but now the 2nd male is quite bright, although not perfect. He's the one lurking in the juvy photo I posted. I have long worried that something mysterious and non-fatal infected them in their old 55g tank. Something that causes just enough stress to leave them feeling only about 80-90%, like a minor parasite, but I have no proof of that plus have treated the tank with prazi and levamisole in the past for other things without any change. I'd say I'm just being paranoid but the two juvies that I bought from another source as the rest, which lived in the main tank with the adults til recently, are also color-free, while the 14 others their size from the other source are brilliant orange.
Attached below are pics of the original male when I first got them and more recently, orange-free. Same fish. I agree - without the orange, they're quite boring. Since they were orange before, I'm more upset by this than I would be otherwise.
Interestingly, during a filter cleanout where I was forced to flush the ceramic powder from the bottom of an Eheim Classic, causing the tank to become hugely cloudy, all 3 of them showed full orange heads, with black throats and black pelvic fins - they obviously liked the dirty tank.
I have noticed this with mine too. I haven't really clouded the tank, but when doing WCs, the slightly cloudy water plus lower water level changing the way the light hits, they get slightly more orange. Part of me wonders if I should just bite the bullet and put some new driftwood in to leak tannins into the water. My monster tank had that going on for about 6 months though and I hated the tinted water.
In your case, if you have an established colony or pairs of Orange Heads in the tank, I'd say give the altifrons a shot - you can always sell large Eartheaters without too much of an issue (over in Australia you can anyway), so if it doesn't work out there's really no harm done.
Well, if I get a few Altifrons or Abalios I'm going to get them smaller, just because I'd prefer to let the Tetras live out their lives naturally rather than getting eaten. So I would hope that wouldn't be a problem. And I am pretty sure I have the tapajos variety, although really, I have no idea how to tell. We'll see what the swap meet on sunday has as far as other eartheaters. They're usually very African-centric, so there might not be any good geos at all, or maybe I'll hit the jackpot. Who knows. If I don't end up with anything else it's not like I'll be at a loss for fish. The only thing I really need to get is a couple more jurupari since I have just one. Tough to find legit jurupari though, since they're all really leucosticta over here.
Hopefully I have more luck with my tiny little colony growing up in the 75G. Much better chance at a better ratio of sexes and they'll be the dominant species once they outgrow my dorsigera (not that they're in any way dominant).
Well, if my luck with the younger ones vs. the older ones is any indication, your little ones will do much better.
Have you found your dorsigera to be especially sensitive to water conditions or anything? I had 4 of them, really like them, but have had terrible luck. I lost three between about 3 and 8 months and the last one, which I've had for maybe 9-10 months total, is looking awful, has a white zit on his head, and has been hospitalized. I've never heard of anyone having problems with them... maybe I just got a bad batch. They did come from a Petsmart, after all.
