Anyone know what fish this is?

Recommended Posts

Hey there, A while ago I caught some wild galaxias and this is one of them. They were captured just outside of the Abel Tasman reserve at Marahau (I know one is an Inanga/Common galaxias and one is some sort of kokopu (probably banded)) but the third one I have no idea as to which species it is. Picture attached, if anyone knows don't hesitate to reply! Also, yes, I am keeping these with "tropical" fish in an unheated tank.

Stella has only had a brief look as she is sick at the moment but she wonders if they might be dwarf galaxias as she says there is something different about them but the distribution fits.

She also asks to remind people to not remove fish from their natural habitat if you don't know what sort it is and their requirements.

Okay, well at first we caught them from a large shoal of young fish. We thought that they were Inanga as they are common, are (fairly) small and form large shoals but it turned out that it was a large shoal of different species, we only discovered this after acclimatising them to the tank as only then were we able to properly see their patterns. I just also did a google search for Dwarf Galaxias but I dont think it's them as they're much more colourful and look to be smaller in size than my fish currently is, however in the related species section I found a picture if a fish that looks quite similar to mine (Galaxias olidus). Still not sure if this is it since the patterns are more dense but it looks close. I suppose it could also be a Spotted Galaxias, however I'm not sure if they are in New Zealand or not, aswell as the spots on the fish being smaller and further apart. Picture of Galaxias olidus attached below.

Also on a second look my fish and this do look quite different, but I'll keep the image here for reference

Ok, cool. I did some more research and found a type of dwarf galaxias that looks like mine, however it's behavior looks very different as it seems to like hanging out on the bottom and not doing much as seen in a lot of the pictures I saw, and mine is very active and seems to hang mid tank, however this behavior could be induce by it schooling with the other whitebait.

This is the Australian dwarf galaxias and is the reason why I didn't think mine was one (They look very cool by the way):

This is the New Zealand one (It appears there are actually many different species of galaxias called the Dwarf Galaxias, which is silly if you ask me but whatever):

My Galaxias's spots are beginning to change and look slightly more like this but it still looks pretty different if you ask me, just the patterns look close-ish as well as the colour.



Edit 2: Went home and took this photo, the spots are definitely more vivid in colour now, but the patterns are still nothing like dwarf galaxias.


EDIT: This fish could become very hard to identify if it is indeed a dwarf galaxias, as there are a lot of very similar species with very few differences
