Leave them alone and let them do their thing. If all that is in there are the two Geophagus and the Acarichthys growouts, they will be fine. If these are wild fish they might surprise you how well they can do if left to their own devices. The male sounds aggressive and that will be good for keeping the other fish away and it won't be too tough to do so with Geos and young heckellii. You can at least determine their abilities and base future decisions on that. I think it would be a shame to strip them.

Why is it a shame?
 
Sorry jgentry, I wasn't directing that at you or your advice in any way, other than meaning that I would not do it. It's just my opposing opinion, that it is unfortunate that has become common practice. IF any aspect of parental care is learned, it is then lost. Or IF there is any benefit from early exposure to their parents, it is lost. I'm not saying that I believe that fully, but if given the choice, I would rather have fry raised by their parents during their early days/weeks than by a human. Just in case.

coz I'd miss the fun too :)

Ed gave me the same suggestion on the tapajos, and he turned out to be absolutely right - I took half of the fry out and left half with the parents. so far it seems that those with the parents (in a 55g) are growing slightly faster than the other half (in a 10g). I'm considering putting the other half back....

Same thing with my balzanii - left some fry with the female and they did great, until they were ~4 weeks old and the female refused to pick them up even when I "threaten" them.

So I think Ed is right and I should give the this couple a chance. There are 6 more severums that are similar in size to this pair, 6 heckelii around 3-4", and a few Geos. No catfish or pleco.... I'll leave them alone for now... :)

No worries, I didn't think it was directed at me. I was interested in hearing your reasoning and why you do it a certain way or suggest a certain way. I'm just trying to learn from as many different opinions as possible:D. I'm not experienced with mouthbrooders, so I'm just trying to learn from people with experience.

My experience from other severums is that it won't work all to well in a mixed community environment. Parents always seem to stress and eat them.
 
Well, I don't actually know ;)

The larvae were picked up just short of two days after they laid, perhaps a few hours earlier than the first couple of times but still normal (I guess!). The female are definitely holding, and the male might be as well; both are staying near the spawning site where only egg shells and a few white eggs remain.

IME the wigglers should become free-swimming in the next couple of days. The earliest I've seen the female release the wigglers was 4-5 days after spawning, but that was with a divider and she must have felt safe. Will mostly likely take longer this time.

If they are able to protect the fry I'll leave them alone as Ed suggested. If not, well we'll see. They are dominant fish in the tank but the heckeliis can be fast and sneaky :(
 
pics as promised :)
