heros!

Recommended Posts

Hi there have had this pair of geophagus surinamensis for about 8months.there about

16-17cm long and have spawned 4 times now, and the eggs wont seem to hatch and turn white about

72 hours later just when i think there about to hatch.tank is 5ft/2 by2 1/2deep,filter is 4ft sump,water seems 100%.

does this mean male is infertile?

really need your help very frustrating :help:

I had this trouble with a pair for severums with a definate sexed pair, I even swapped the male.

One theory is that if the water is too hard, the eggs can't hatch - tho I would more lean towards them not being fertilised in the first place.

It could be that your pair (if you do have a male) just needs more practice, or they could be infertile.

I am no expert on geos but I always thought the male's finnage is in most cases longer/more elegant but the fins on these two fish look the same imo so wouldn't that point to two girls in most cases?

Hopefully a geo expert has a look at this thread and can shed some light.

Its not to clear but the fish at the back "male" has longer bottom fins and if u could see its tail it does too.But would like a geo expert to have a look.

Looks like 2 female,they are a very hard fish to tell.

Notice the finnage on this Brachybranchus. This is a female so finnage does not always show the sex of Geos.

Is there any flaring of gills and sideslapping before a rock is chosen and eggs laid? A female doesn't need a male around to lay eggs.

Thats a very nice fish could that be the same species as myne?

not really sure what myne are just going of other pics.

they were in bad cond when i bought them with no name.

but one always chases the other around till she lays.They both puff up thier gills and get strong black under thier mouth but only seems to be one that lays and displays egg tube.

help with correct species would be great thanks.

I would say yours are Brachybranchus as the "Surinamensis" is a myth really(years ago maybe they were around but not now).

As for breeding, the female will lay a line of eggs(usually a straight line)and the male will swim over and fertilise immediately,then the female will lay another line and the male fertilises them,again straight away and so on until all eggs are laid and fertilised. The eggs are then guarded for 24-48 hours before being picked up and mouthbrooding commencing. 48 hours being the utmost time i have ever seen. Mine usually pick up after about 24 hours at a temp of 28 degrees.

G'day

I had the same problem, the only thing different for me was their first spawn was a success. (So there were no possible gender related problems).

Anyways... every single spawn afterwards was not. Every single time the eggs suffered from fungus.

I tried absolutely everything, pH higher, lower, temp, up down, more air, different filters, hardness higher, lower, live foods, flake, pellets. It took me over 18 months to solve the problem. In the end it was quite simple.

The eggs were going bad because of a lack of water flow (Oxygen) over them.

To solve the problem I invented a spawning platform that was powered by an air (water) uplift tube.

I actually wrote this in an article for the NSW Cichlid Society, wish I had kept a copy of the article.

Sorry but I do not have a pic of the platform atm. The fish are asleep, their lights come on later today.

Hope this helps.

Thanks matt so your saying i neen flow around the eggs,like an air stone or power head would this help?

G'day

I have tried both of these options (when the pair did not spawn on "their" platform). To mixed results.

Airstone: You must not allow the eggs to get air around them, ie direct contact

Powerhead: Dodgy suction caps and two different powerheads moved and the result was not good. If you use this method, not a lot of water movement is needed, so I was bouncing it off the back wall before it flowed over the eggs.

Anyway here are some pics.

Yes I know they are not brachys but they have spawned on the platform once, even though they are not supposed to.

PS. Why is it that if you want to take a photo of a fish it will be gone and if you want them to move, the buggers refuse? :dntknw:
