Mogurnda mogurnda?

[ste12000]

Hi all, a friend of mine picked these fish up from a recent auction, they came from another friend of mine and as far as i can make out have not bred for either keeper, there are 5 fish in the group and after seeing them yesterday im pretty sure there are both sexes.. From the picture below are these Mogurnda mogurnda aka the Northern Purple Spotted Gudgeon?

My friend wants rid of these fish and im tempted to get them as a interesting breeding project.

Ive never kept Australian species of fish, is anyone aware of the seasonal fluctuations and potential breeding triggers for these fish?? Ive read the general info online and the excellent SF Knowledge base but cannot find too much accurate breeding info.

Cheers, Ste

Had them some years ago. Bred well in pvc pipes, the males taking care of the nest.

I used to take the fry apart when they were free swimming and had no problem in raising them up.

Hard alkaline tap water here, I kept them between 22 and over 30 ºC, no problems at all. They will eat smaller fish if they have the chance, but otherwise, quite good tempered.

No fussy at all with feeding, but be careful, they tend to eat far too much, perhaps don´t feed them once or twice a week.

I think they come from Papua New Guinea Steve? Dont think the Aussies have let them out for a long time… depends on the original source I suppose but probably not Aus.

I bred them in 1997 or 98 and they spawned in a clay draining pipe about 3″ diameter and 12″ long. The male used to eat the fry after about ten to twelve days so get him out as soon as they are free swimming

They’ll also just use the tank glass if no caves available. We had a couple of pairs spawning in a stock tank at Tom’s shop on one occasion. Didn’t raise fry though…

Guess you’re right about collection Colin, or they might even be commercially-produced these days?

Cheers guys, im beginning to wonder why this particular group have not spawned? the two keeper friends of mine are certainly not beginner breeders? if they are classed as easy fish that spawn even in shop tanks(no matter how good the shop is) then its a puzzle why my two friends have not bred them?

These are LARGE fish at almost 5inches so i might just leave them and maybe start my first goby project with something younger and smaller. My fishrooms not setup for larger fish..

Are there any particular spawning seasons in Australia and Papa new guinea??? do they have wet and dry seasons that may trigger these fish off?

These would possibly be the Mogurnda “Irian Jaya” that BAS imported a year or two ago?

Could it be simply that not every group of fish can be spawned?–for whatever reasons.

Specifically, with Mogurndra, it appears that some groups are easy, but a local club member (certainly not a beginner, I think more than 200 species to day,including some similar to M.M.) also spent a year trying to spawn his group and gave up on them. I have a healthy looking group of rainbows (about the easiest to breed, right?) I cannot get a single fertile egg for two years.
