Geophagus winemilleri spawned


Arowana blogger
Just before going to bed last night I noticed a pair of my Geophagus winemilleri had spawned on some driftwood in my 300 gallon. I assumed my group of large clown loaches would eat the eggs overnight. Today the eggs are still there and the parents are standing stiff guard against all intruders. And now I seem to have another pair of winemilleri acting in breeding mode. My kids are excited, so I might just go through the trouble of getting set up to raise fry. I have never raised F1 fish before, so it would be something new.

I'd say there is a pretty slim chance of them making it this time around. I have someone taking my clown loaches soon, so once they are out of the picture the odds should go way up.

Thanks Mike, yes these guys are well established I think. They have an interesting "breeding display" - lots of chasing, puffing up, and colouring like male peacock birds; beats TV. :)

Congrats on the spawn theo...
Maybe i should keep some geos too...
Sadly.. i never breeded anything other than killi fish and guppies hahaha.....
maybe my rays will have a chance when they mature but no so sure if its possible in a tank of preds....



I have always had very poor luck leaving the eggs with the parents I have had much better results pulling the eggs and raising them on there own.

The secret it Methaline blue lots of it.

I pull the eggs stick them in a 5- 10 gallon tank and dose with Methaline blue until you can barley see the eggs.
I add an airstone and adjust the air so that the eggs are being vibrated around but dont float away.
this prevents them from fungusing.

as soon as they hatch I do a large %75 water change then %50 daily water changes.

I always use water from the parents tank

Add a sponge filter once there is very little methaline blue left as it will kill the bio

on the third day or so when they are free swimming I start feeding them live baby brine shrimp.

good luck those things are real beauties

Thanks Bluebase, and thanks for the tips Graeme. A long time ago I raised baby oscars and angelfish using the exact technique you mentioned; though I used corner filters with charcoal to take out the methylene blue over 3-4 days (the time needed to hatch the eggs). I also used pieces of nylon stocking over the filter box to keep any fry from getting sucked in.

I now think that the clown loaches did not in fact eat the eggs; I think they hatched and the parents took them in their mouth at that time; I am feeding them crushed fish food now with a turkey baster, couple blasts per day. At this rate they will make an inch in a year. :rolleyes: Since the parents are doing such a good job raising the fry right, I have decided to just let nature take its course. Next time I will try to raise them with baby brine shrimp, etc.

The fry have gotten a bit bigger, but it is time for me to take them out of the 300 gallon and into a smaller tank to properly raise them up.

I am going to set up a 10 or 20 gallon tank tomorrow to transfer them into; my young son has pointed out the obvious question - "How are you going to catch them?" Anyone have any ideas? :) I am thinking I will have to net the parents and then try "stripping the eggs from them? That approach makes me nervous, but I can not think of another...


I have stripped a few Geo's sometime you get luck and they will spit the fry out when you net them.
