ID: Gudgeon? - Mogurnda spp. and Tateurndina ocellicauda

[joydiv]

Got four of these fellow. Wonder what's the scientific name for them. Any tips on caring for these?

[mickthefish]

hi joydiv
i'm not sure which type it is but the first name is Mogurnda, it's possible that it could be M. dispersa .
but whatever the species you are looking at a fish that will attain at least 6 inches SL.

thanks, will have to prepare a bigger tank for them. Any diff between the male and female?

[mickthefish]

hi joydiv
the difference is mainly in colour, the male being the brighter of the two.
in your two pics they are a pair the male being the 1st pic.
i have only bred the M mogurnda, and i can say you get loads of young and they were very intresting to breed.

If these are M. adspersa, here is an article from Practical Fishkeeping that may interest you. (Need to register - for free - and login to read the article though)

Excerpts on identification:

Identification: This species has fewer scales in the lateral series than M. mogurnda (30-36 in M. adspersa, compared to 37-46 in M. mogurnda). Red spots are present in the middle and upper parts of the second dorsal fin in adspersa. In M. mogurnda the second dorsal has fewer, larger red spots, confined to the bottom of the fin.

Thanks for all the information. Here's another Pic

Another Gudgeon. This time M mogurnda. Much more colourful.

Looking at the plants in the pictures, they are all housed in the same tank? I guess you have no intention of breeding them then? Thought that would be an interesting probject.

[joydiv]

Oh I shifted the two big fellas into another tank. Couldnt find the female for the M morgunda though.

I had a few of these, but they are actually rather aggressive fellows! In the end, I'm still left with one. Currently looking for a few more, but can't seem to find them lately.

i think i saw a few of them at wuhu (the lfs at tiongbahru) today.

Another Gudgeon. This time M mogurnda. Much more colourful.

Hope I don't come across rude but I don't think thats a mogurnda at all.
Looks like a peacock gudgeon (Tateurndina ocellicauda) from Papua/New Guinea regions.

I could be wrong,I am really good at that ...

The other shots are of a mogurnda.Mogurnda grow much larger than peacocks.A full grown one could be over 200mm.Any fish that can fit in its mouth is possible food.The peacock is much smaller and more community friendly.( I currently have about 12 of them in a Australian native tank )They only grow to about 60mm or so.

Graemes right about the mogurnda.
They will eat almsot anything that will fit in their mouth.
Mine have eaten Neon tetras and Threadfin rainbows. The mogurnda at the time was about 70 mm long.

Mine 8 cm specimen swallowed the rummy nose tetra whole!!! It even tried to eat a betta that's 3/4 it's size. Not very intelligent.

Cheers,

Guess the fish shop which sold the fish to me was wrong then. Thanks for all the information.
