heros! Posted July 25, 2007 Share Posted July 25, 2007 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 Link to comment Share on other sites More sharing options...
Barca888 Posted July 25, 2007 Share Posted July 25, 2007 It could mean that it's infertile or they like same sex action like Oscars. Link to comment Share on other sites More sharing options...
electricyellowz Posted July 25, 2007 Share Posted July 25, 2007 they like same sex action like Oscars. Thats what I was thinking that it could be two girls. SOme photos of the fish would help to sort that out. Link to comment Share on other sites More sharing options...
Ash Posted July 25, 2007 Share Posted July 25, 2007 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. Link to comment Share on other sites More sharing options...
heros! Posted July 26, 2007 Author Share Posted July 26, 2007 hard to get a clear shot of both, think males at the the back.will try and get better shot later if this wont help. Link to comment Share on other sites More sharing options...
electricyellowz Posted July 26, 2007 Share Posted July 26, 2007 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. Link to comment Share on other sites More sharing options...

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.

chevguy Posted July 26, 2007 Share Posted July 26, 2007 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. Link to comment Share on other sites More sharing options...

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.

chevguy Posted July 27, 2007 Share Posted July 27, 2007 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. HTH Link to comment Share on other sites More sharing options...

Matthew Posted July 30, 2007 Share Posted July 30, 2007 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 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. cya Matthew Link to comment Share on other sites More sharing options...
heros! Posted July 30, 2007 Author Share Posted July 30, 2007 Thanks matt so your saying i neen flow around the eggs,like an air stone or power head would this help? Link to comment Share on other sites More sharing options...
robdog013 Posted July 31, 2007 Share Posted July 31, 2007 They are both females mate at that sixe the MAles usually develop long fin extensions, put up a wTB add Male surinamensis...... a lil girl on gril action never helped nothin Link to comment Share on other sites More sharing options...
Matthew Posted July 31, 2007 Share Posted July 31, 2007 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? cya Matthew Link to comment Share on other sites More sharing options...
