Satanoperca Mapiritensis Holding (EPIC DAY FOR ME)

[darth pike]

About bloody time!!!

You might want to ask Wayne if Lee Newman has bred them ... I imagine if anyone in North America has, he'd be the one. I certainly haven't seen any breeding reports.

Not sure if I'd strip her though, it can be stressful and these aren't exactly a common species after all.

It might be worth two tanks of gas just to head down there and see the fry once they are free swimming though.

Thanks for the comments guys!

Congrats!! Very nice work

Did they spawn on a rock and are they delayed mouth brooders?

Thanks Peter! They spawned on oak leaves that they had been courting over/the male had cleaned up and prepared for her for about 24 hours to the best of my knowledge. Unfortunatly I was at work when they spawned so I cannot say for sure, but I'm 95% based on the behavior leading up to her brooding. IME so far this species could care less about stones of any size, surface roughness or shape. They are more interested in leaves than anything else I've tried. I have been waiting to answer the delayed or immediate mouth brooding question for a while. The eggs were picked up at the latest within 8 hours to my knowledge. I checked on them in the morning and she was not brooding anything.

It shouldn't be too long before they give it another go, I'll cross my fingers and report back anything I notice.

Thanks Chris. I spoke with Oliver Lucanus and he suggested I ask Lee as well. I have a message out to him but have not heard back. My message was asking for advice though, they had not spawned at that point, they were only courting. I'll reach out to him again. Your right on stripping the fry, I'm getting ahead of myself. This species does NOT do well with stress so I am pretty reluctant to push it like you said. I would prefer to let them have a few go's at it until they figure out what they are doing.

They are in a 120 gallon with x15 Hyphessobrycon colombianus and x3 Corydora sterbai (also spawning lol..). If anything, I'll remove everyone else if she does not release the fry.

Impressive! Congrats, that is a big deal and a great acomplishment. I wish you luck in raising the fry. Great job!!!!

Congrats dude!

The fact that it was oxygen levels that triggered it is interesting. It makes me wonder if in the wild they migrate to whitewater rivers to spawn or if the extra oxygen simulated the end of the dry season.

I agree that it's a good idea not to strip her on the first go, plus imho getting to see the actual behavior of mouthbrooding is probably the best part of keeping mouthbrooders.

Thanks Colin! Funny I was just having that conversation with Jeff last night. This is opinion based obviously, but I think the disolved O2 level increasing mirrored the begining of the rainy season as well. Not to say they do not travel out further into clear/white waters to spawn but most fish who do, spawn on stones correct or in deeper pits? The fact they are more interested in slow flow and things like leaves over all else to me points to the end of the rainy season over white water. Thoughts?

Though this isn't even the same genius, yours spawning on leaves reminded me of the G. gymnogynes I photographed in Uruguay! It makes sense that they'd spawn in the calmer pools rather than in rapids because of losses due to fry being blown away. I'm curious what others have to say and what you find out! Btw if no one knows the answer how about a group of us grab a plane and a guide to go see for ourselves

Wow awesome justin. Thats great that you got them to breed. Not every day a rare geo gets bred.

I would say that it recreating the start of the rainy season is probably the more likely of the two, as that seems to be a common spawning trigger for many south american fish. My boss at the aquarium is also pretty interested in eartheaters so I will definitely be showing him this thread. Who knows, maybe we will start adding leaves to the satanoperca tanks .

Looking forward to the fries!

Thanks for the pic Armond! I am jealous I would have loved to go on one of Ken's trips. I doubt any new info is going to come about from this species but if nothing else, we can tack a yes or no next to a few questions.

Thanks Jim!

Thanks Ryan!

Agreed. The Oregon zoo have about x12 10"+ S. lueco's in with a huge anaconda. Amazing display. I'll email you some pics.


Day three and she is still holding. [crosses fingers]
