Phillip Posted August 14, 2022 Share Posted August 14, 2022 Do we have any Apistogramma gurus in here? I bought these as an “attempted pair.” I used to be able to tell the difference between the two. Now they both look the same to me. Do I have a pair? Also, I don’t know why it uploaded sideways, and I don’t know how to fix it 🤣 Link to comment Share on other sites More sharing options...
tolstoy21 Posted August 14, 2022 Share Posted August 14, 2022 (edited) I wont to claim to be an expert at sexing super reds (especially younger fish), but I can share some pics of a male / female pair I have at the moment (I have another female and she looks exactly like the female the pics below). The key differences I notice between my male and females are as follows: The male is maybe larger than the females. If I were to guesstimate, I'd say its larger by maybe 30-40%. The male is the only one I have to exhibit the purple coloration along the base of the dorsal. The males tail is much more vibrantly colored. The dorsal and anal fins in the males are much more exaggerated (as is typical many apisto species). Again, this is just what I've observed in I'm my current trio. I have some fry growing out, but I just haven't spent enough time to feel confident I've mastered sexing agassizi variant. Ok now for some pics (taken moments ago).

anewbie Posted August 14, 2022 Share Posted August 14, 2022 Agassizii don't pair; they are harem breeders with the male establishing a territory and claiming all females in that territory. The number of females depend on size of the aquarium and scaping. These are very important factors since the female will be aggressive to the male when she lays eggs and vice versa the male will chase female out of territory when they are not ready to breed. As to your specific question on the sex - i can't tell much from the pictures - they could both be males but the picture isn't very good. Also what size are they (are they mature?).

They are around 6 - 8 months old. They sleep in the same coconut cave every night which made me think one male and one female 🤷🏻♂️ Link to comment Share on other sites More sharing options...
tolstoy21 Posted August 14, 2022 Share Posted August 14, 2022 Ok, so adding to my prior post . . . . based on coloration, I'm leaning towards two males. But as @anewie said, the pics are hard to see, but the top (left) fish appears to have much a more elongated dorsal than I see in my females. Hard to see in the bottom (right) fish. But I would say if their dorsal and anal fins are getting close to being as long as their tail, then you might have 2 males. 1 Link to comment Share on other sites More sharing options...

I've had success breeding these fish in pairs. I only breed them as pairs, and not in harems, because the tanks I have aren't conducive to harem breeding, and when one female spawns, the other gobbles down her fry pretty fast.

You have a harem it consist of one female 😉 1 Link to comment Share on other sites More sharing options...

One of their tails was seemed to be a male at first. Sleeper male maybe?? This is the one that looked male to me a couple months ago.

Sleeper male maybe?? Based on your first pic, these fish appear similar in size. By 8 months, the male should be noticeably larger than the female. I also have Agassizii double reds, and the male is noticeably larger than his mate. It's similar with Cacatoudies as well, in my experience.

But . . . . . I could be wrong! Like I said, would not consider myself to have mastered sexing this variant by any degree as of yet. Link to comment Share on other sites More sharing options...

I would’ve thought they’d be aggressive toward each other?? Agreed. The finnage and coloration says male to me, but . . . . yeah I'd expect them tussle over territory. How large is your aquarium? I have found that when I grow out a large number of fish together they are pretty peaceful with one another because the idea of claiming territory is meaningless. Not sure if two semi-grown males in a similar circumstance, without the presence of females would result in the same. On the other hand, I've had a particular A Cacs. male that would kill any other male I put in a 125 gallon. Link to comment Share on other sites More sharing options...

If they both exhibit elongated fins in an identical manner, and are roughly the same size, then they are the same sex. Coloration can vary to a degree, but fin shape/length and overall size difference should be key indicators.

anewbie Posted August 14, 2022 Share Posted August 14, 2022 Couple of comments: while typically the female is much smaller that is not always the case. Two males with no females might hang out together. They seem to only become territorial when there is a reason to be territorial... 1 Link to comment Share on other sites More sharing options...
