A. rivulatus challenge

[MrsE88]

Does anyone know how to tell apart a normal GT vs a shortbody GT at the juvenile stage around 2"~4"?

I would think anyone should be able to see the difference just like any other short body fish.

Agree with previous comment, all short body fish look scrunched up, even when juvies.

Please help me take a look whether these two GTs are normal or short body..
GT1 (pic 1 - 8)
GT2 (pic 9 - 12)

I got them both from the same batch and now they are roughly 3"~4"

Yes, I would say they are short bodied.
The back half looks a good bit shorter then normal.

For whatever reason it's common to see 'care sheets' say they get 12 inches and this has got into people's heads. The truth seems to be they vary some in size, but not many get 12".

Which is what makes me wonder about blombergi. Everything I've seen says they max @ 6 inches, but that's descriptions of the wild fish-- will they get a bit bigger in a home aquarium?

I’m sure, 7-8” would be a normal well cared for fish in an aquarium setting. Is blombergi even in the hobby anymore? Was it absorbed by confusion and bred into rivulatus? There is almost zero info about them and only a couple pictures of them.

No idea. I question how many were actually imported in years past, at least to the US, correctly identified or not. Not to be dogmatic, but I'd want to see evidence I've yet to see of them.

I couldn't predict whether they'd exceed wild sizes by much, just a question imo. How many 8" A. pulcher or A. biseriatus are out there?

Right, most are in the 6” area. Good stuff in this post. Guess until a positively identified Bloombergi is imported we will never know.

Agree with Mrs E88 on the photos above, one of them especially, the other I'm not as sure of with the camera angles. Sometimes in normal spawns of various species you can get oddballs with short bodies and it can happen to different degrees, some can be more severe than others.

They were both the last remaining GTs available in the LFS so in a sense, I picked the runts of the litter

I think I found the winner. If it wasn't such a long drive I would have gone with a tape measure & camera, just to check it out. Approx 14" , and due to its extreme rarity, priced at only $350. Aquarium not included.
