Krobia guianensis spawn

  • We are currently upgrading MFK. thanks! -neo
I moved all my Krobia guianensis growouts into my 150 which is now super crowded. Out of ten fish, I have three pairs with a fourth trying to form. Here's a video of two pairs spawning within a few inches of each other -- you can see they don't appreciate the close quarters. ;) If this is deja vu for you, it's because I posted it in another thread recently.

The eggs have been disappearing after two days. They all looked good so I don't think they were infertile. I think the pairs have been eating the wrigglers. Finally, earlier this week, I caught my female guarding some driftwood after her eggs disappeared. I came home today to find about 50 fry tucked away in a pit under the driftwood. I have my first confirmed pair.

Anyone want to buy a pair of young Krobia guianensis? :ROFL:
 
So far the males are 4 - 5" and the females are about 3". Apparently, like Geophagus brasiliensis, they spawn at a small size and early age. They're not even a year old yet. The males recently hit a growth spurt when I moved them to my 150 and they seem to be getting that taller, chunkier shape that I love so much on the acaras.
 
I'm curious to know how large they get. 4" at a year is pretty impressive. They're breeding dress is quite nice too.
How would you compare these to xinguensis? The orange flanks on those are pretty damn irresistible!

They are totally different fish. My xinguensis could be rough on each other, but they were also pretty shy. They tended to do best in a community setting with outgoing and personable fish. It brought them out of their shells a bit. I much prefer the color of the xinguensis, but the guianensis do have an understated beauty. The breeding dress is nice. Overall, I'd say the guianensis have very similar color and patterning to a keyhole cichlid most of the time. They tend to be a tan/brown color. Right now they're showing some nice red in the fins but I haven't seen that in pictures of adults, so I don't know if it fades or if I got lucky.

Size is anybody's guess. A few things I read online said the largest caught is 127mm, which is about 5"? But then a member here said his male is way bigger than that. My Krobia xinguensis topped out around 6 - 7" for males, 5 - 6" for females, so I'm thinking around that size.

In terms of attitude, the guianensis do not let other fish push them around. I have never seen them be aggressive to tankmates but they were definitely harder on each other once they hit about 4" and started breeding. My females were all shredding each others' fins which is why I moved them into the 150.
 
Congrats on the fry Ryan! You have now joined the Kroba breeders club............lol. Parents look great, good luck with them. Are you going to pull the fry or try and let the parents raise them in the big tank?

I did something that's never actually worked for me... until now. I set up a 20 long, moved the parents to it, then siphoned in the fry. I've tried this in the past and the parents usually get stressed and eat the fry, and/or one of the adults attacks the other. Instead, the female dug a little pit and both parents moved all the fry to it. Here they are this morning:
