nuchal manParticipantCongrats on the spawn and those are some great pics, it’s not an easy fish to get fry from. Here are some bad photos of the ones I was working with at the Shedd Aquarium in Chicago when I was interning there. The babies have an adorable color pattern.

ColinParticipantGood pics none the less!

StefanMemberWell done both of you!
They certainly represent an interesting ‘niche’ in labyrinths Colin!

MattKeymasterBrilliant.

betaParticipantSam: Those are some excellent pics. Do you recall how many fry per spawn you got. I count less than 10 in my tank. What did you offer as a first food?
Matt: I keep mine in fairly hard water and the temp is around 28 C. I think we need to update the knowledge base article as I feel they are paternal mouth brooders. Maybe Sam can verify?

nuchal manParticipantThey bred in a community 500 gallon asian community display. The water at the aquarium is from Lake Michigan and is about 7.6-7.8 pH and it’s very hard, pretty much liquid rock. There actually was an ich outbreak on the display and some salt was added to the tank. They spawned after a few water changes from this point.
Water temp was around 78-80F. I completely agree with Beta, they are a paternal mouthbrooder. I was surprised at the amount of fry the male was holding. He spit about 70, and they are pretty good size. First foods were baby brine shrimp and copeopods.
I found this species to be jumpers and I had issues with high levels of conspecific aggression, even in a 500.

MattKeymasterThanks for the info guys, will make the necessary changes asap. Are both sexes aggressive towards one another?
August 9, 2011 at 9:02 am #344928
nuchal manParticipantI didn’t see any difference in aggression between males and females. For such a fragile fish, they can be quite nasty to each other.

betaParticipantOnly 3 survivors!
Here is a video of one of them taken on my mobile cam.August 30, 2011 at 9:35 am #345045
MattKeymasterOh no.

MattKeymasterColin and others, what level of intraspecific aggression have you experienced with this species?
November 9, 2011 at 4:34 pm #345996
ColinParticipantA lot!
Once you get a dominant fish they keep harrying the rest of them, I have 6 in a tank now and you always have a dominant fish
BUT there are no injuries and no split fins, just chasing

MattKeymasterIs the alpha individual male or female Colin, or does it vary?

ColinParticipantI dont know how to sex them yet…. will keep an eye on the ones i am keeping though
